✏Copper Zinc Tin Sulfide Based Thin Film Solar Cells Book Summary : Beginning with an overview and historical background of Copper Zinc Tin Sulphide (CZTS) technology, subsequent chapters cover properties of CZTS thin films, different preparation methods of CZTS thin films, a comparative study of CZTS and CIGS solar cell, computational approach, and future applications of CZTS thin film solar modules to both ground–mount and rooftop installation. The semiconducting compound (CZTS) is made up earth–abundant, low–cost and non–toxic elements, which make it an ideal candidate to replace Cu(In,Ga)Se2 (CIGS) and CdTe solar cells which face material scarcity and toxicity issues. The device performance of CZTS–based thin film solar cells has been steadily improving over the past 20 years, and they have now reached near commercial efficiency levels (10%). These achievements prove that CZTS–based solar cells have the potential to be used for large–scale deployment of photovoltaics. With contributions from leading researchers from academia and industry, many of these authors have contributed to the improvement of its efficiency, and have rich experience in preparing a variety of semiconducting thin films for solar cells.

✏Highly Efficient Solar Cells in Low Dimensionality Based on Cu In Ga Se2 Chalcopyrite Materials Book Summary : In this thesis we explored the potential of thin film microscale concentrator solar cells. The aim of the study is to develop a highly efficient photovoltaic technology, based on large-area processes for high throughput, and which is raw-material thrifty to meet the constraints of terawatt development. The miniaturization of thin film solar cells leads to a low resistive architecture, with easy thermal management, which is therefore adapted to the concentrating regime. The scale effects are studied from an analytical and numerical point of view. Prototype Cu(In,Ga)Se2 solar cells are fabricated with help of photolithography techniques and tested to evaluate the performance of the microcells. A 5% absolute efficiency increase was measured, which led to a 21.3% efficiency of a 50 μm diameter microcell at a concentration of x475. The influence of the incident spectra is highlighted. The specific features of the high illumination regime are studied for the first time on Cu(In,Ga)Se2. The photoconductive behavior of Cu(In,Ga)Se2 is analyzed. The screening of the electric field in the Cu(In,Ga)Se2 heterojunction under high light fluxes is evidenced by simulation and may explain the influence of the illumination level on the collection efficiency observed experimentally. The possibility of an industrial application is tackled via the fabrication of mesa delineated microcells, which proves that the edge surface of the microcells have a low recombination velocity (

✏Solution Processing for Copper Indium Sulfide Solar Cells Book Summary : In recent years, the field of photovoltaics has become increasingly important due to rising energy demand and climate change. While most solar cells are currently composed of crystalline silicon, devices with thinner films of inorganic absorber materials might allow production at a greater scale due to their lower materials cost. In particular, thin films of CuInS2 are promising solar absorber materials due to their high efficiencies and low required thicknesses. However, the fabrication of thin film solar cells currently requires expensive vacuum techniques. As an alternative, solution-based deposition techniques have been proposed as a route to low-cost and high-throughput electronic device fabrication. I have studied how film growth depends on solutuion deposited precursor film quality, with the goal of producing large grained films of CuInS2 through solution processing. In the first approach, we used solvothermal decomposition of organometallic precursors at moderate temperatures to produce nanoparticles of CuInS2. Thin films of these nanoparticles were cast onto molybdenum coated glass and further processed to create CuInS2 solar cells. We found that performance was dependent on film porosity, grain size, and stoichiometry of the nanoparticles. Films with grain sizes of ~200nm were attained, from which 1.3% efficient solar cells were made. In addition, we showed that this synthesis could be extended to produce CuInS2 nanoparticles with partial substitution of Fe, Zn, and Ga. In the second approach, we synthesized an air-stable hybrid organometallic/nanoparticle ink at room temperature in ambient conditions through a vulcanization reaction. This ink could be coated onto substrates in smooth layers, and further reactive annealing formed large grained CuInS2 films. This process was characterized, and a correlation between residual carbon and grain growth was found. Additionally, the chemical transformation between precursor layers and final sulfide thin film was analyzed, with an emphasis on the difference between sulfurization and selenization. We demonstrated that the sulfurization process was producing morphological defects due to its nucleation limited growth mechanism. However, it was modified to more closely resemble the diffusion limited selenization mechanism, thus producing flat films of CuInS2 with grain sizes of ~500nm.

✏Polycrystalline Semiconductors V Book Summary : Like the previous conferences in this series, POLYSE '98 covered many aspects of polycrystalline semiconductors. Whereas earlier proceedings had included many contributions on basic research, for example on the structural properties of single grain boundaries, later proceedings had included more articles on solar cells and thin-film transistors, seemingly marking a transition to a more technology-oriented conference. However, the contributions to POLYSE '98 show that the POLYSE-series is again bringing together researchers from basic research as well as engineers working on devices. The 84 papers cover topics such as: beam-induced currents, thin-film silicon, silicon crystallization, oxide semiconductor films, chalcogenide and spinel films, chalcopyrite films, thin-film junctions and devices; thus providing an extensive survey of the most recent results in polycrystalline semiconductor research.

✏High Efficiency Solar Cell Based on Full PVD Processed Cu In Ga Se2 CdIn2S4 Heterojunction Book Summary : Abstract : The original goal of our study is to synthesize by co‐evaporation the phase that could be formed at the interface between polycrystalline p‐Cu(In, Ga)Se2 treated with KF and n‐CdS. Hence, a new buffer layer, CdIn2 S4 (C24), deposited by co‐evaporation is presented for the use in thin film solar cells, exhibiting device efficiencies as high as 16.2%, comparable to that obtained on a reference standard CdS‐buffered device. The physico‐chemical and optical properties of close to stoichiometry 400 nm‐thick films of C24 show similar properties to what has been reported in the literature for single crystals. The layer stack used for solar cells is investigated by transmission electron microscopy, showing the formation of an ultrathin Cd‐deficient C24 layer at the CIGSe/C24 interface, while a clear lattice match is observed at the C24/ZnO interface. Advanced electrical characterizations of the devices suggest that the output voltage and fill factor of the solar cells based on Cu(In, Ga)Se2 /(PVD)C24 are limited by tunneling‐enhanced recombination through extended band tail states. These results open new routes to explain the superiority of wet processes used for the junction formation compared to vacuum‐based approaches. Abstract : Polycrystalline p‐Cu(In, Ga)Se2 ‐thin‐film‐based solar cell is the best performing device when associated with solution deposited CdS as n‐type heterojunction partner. Here, by co‐evaporating CdIn2 S4 as alternative to wet‐processed CdS, the cells achieve 16 % conversion efficiency. The performance of this full‐PVD‐processed device remains limited by lowered junction quality, probably inherent to less‐passivated crystal defects of the Cu(In, Ga)Se2 layer.

✏Electron Selective TiO2 Contact for Cu In Ga Se2 Solar Cells Book Summary : The non-toxic and wide bandgap material TiO2 is explored as an n-type buffer layer on p-type Cu(In, Ga)Se2 (CIGS) absorber layer for thin film solar cells. The amorphous TiO2 thin film deposited by atomic layer deposition process at low temperatures shows conformal coverage on the CIGS absorber layer. Solar cells from non-vacuum deposited CIGS absorbers with TiO2 buffer layer result in a high short-circuit current density of 38.9 mA/cm2 as compared to 36.9 mA/cm2 measured in the reference cell with CdS buffer layer, without compromising open-circuit voltage. The significant photocurrent gain, mainly in the UV part of the spectrum, can be attributed to the low parasitic absorption loss in the ultrathin TiO2 layer (~10 nm) with a larger bandgap of 3.4 eV compared to 2.4 eV of the traditionally used CdS. Overall the solar cell conversion efficiency was improved from 9.5% to 9.9% by substituting the CdS by TiO2 on an active cell area of 10.5 mm2. In conclusion, optimized TiO2/CIGS solar cells show excellent long-term stability. The results imply that TiO2 is a promising buffer layer material for CIGS solar cells, avoiding the toxic CdS buffer layer with added performance advantage.

✏Advances in Thin Film Solar Cells Book Summary : This book concentrates on the latest developments in our understanding of solid-state device physics. The material presented is mainly experimental and based on CdTe thin-film solar cells. It extends these new findings to CIGS thin-film solar cells and presents a new device design based on graded bandgap multilayer solar cells. This design has been experimentally tested using the well-researched GaAs/AlGaAs system and initial devices have shown impressive device parameters. These devices are capable of absorbing all radiation (UV, visible, and infra-red) within the solar spectrum and combines "impact ionization" and "impurity photovoltaic" effects. The improved device understanding presented in this book should impact and guide future device design and low-cost thin-film solar panel manufacture.

✏Solution Processed High Efficiency Thin Film Solar Cells Book Summary : Photovoltaics (PV) is increasingly recognized as an important component of renewable energy sources after the rapid progress in the last decade due to increasing energy demand and reducing manufacturing costs. Despite the enormous growth of the PV market, the present solar technologies that are dominated by crystalline silicon are still limited by the relatively more expensive cost of electricity compared with power generation in the conventional fossil fuel plants. Consequently, there is an urgent need to increase the performance and reduce the manufacturing costs of solar cells. While the commercial thin film solar cells (CdTe and CuInGaSe2) have already demonstrated high efficiencies, the current fabrication processes heavily rely on intensive capital investment on expensive vacuum-based techniques. To reduce solar module costs, solution-processing techniques have been proposed as a promising route towards low cost, high throughput, large scale manufacturing of high efficiency thin film solar cells. In this thesis, we investigate the solution-processing of copper indium chalcogenides and methylammonium lead halides materials and their applications as high efficiency photovoltaic cells. In the first approach, we develop an ultrasonic spray deposition system to prepare the CuIn(S,Se)2 thin films. Spray deposition is a controllable, scalable, and high throughput process that is suitable for industrial manufacturing. Here we first explore the Cu-In-S films prepared by an aqueous precursor ink. By controlling the precursor composition, we fabricate PV devices consisting of the n-type In2S3 window and p-type CuInS2 absorber layers and demonstrate 2% efficiency in the preliminary devices. After replacing the aqueous ink by a hydrazine-based precursor solution and incorporating a selenization process, we are able to fabricate high quality CuIn(S,Se)2 thin film solar cells in both conventional substrate and the backwall superstrate configurations. The efficiency of 7.2% has been achieved in the sprayed CuIn(S,Se)2 devices in the substrate configuration. In the second approach, we investigate solution-processing of the inorganic-organic hybrid metal halide perovskites. We study the impact of reaction temperature and precursor composition on the formation of perovskite materials and propose a pseudo binary phase diagram to guide the processing of the materials. We develop a laser beam induced current (LBIC) technique to spatially resolve the photocurrent collection in the solution-processed devices. Processing defects and impurities phases have been identified as the origins of lower current generation. On the basis of these results, we apply advanced processing techniques in device processing and obtain the champion perovskite device with a 16% efficiency. Additionally, we image the photocurrent generated in the sub-cells of the Si/perovskite tandem devices. The result can be used to improve the design the device structure. Finally, to study the stability of perovskite solar cells, we investigate the spatial and temporal evolution of photocurrent collection across the devices and observe the partially reversible phase transition of perovskite in humid air.
