Book Synopsis Computational Materials Science for Thin-Film Solar Cells by : Hans-Werner Schock
Download or read book Computational Materials Science for Thin-Film Solar Cells written by Hans-Werner Schock and published by Springer. This book was released on 2015-12-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientists and engineers in academic and industrial research experience a strong evolving discipline: Computational Materials Science. This discipline provides materials insights that are not readily achievable by experiments, and it offers the opportunity to design materials and composites “ab-initio”. This book presents the methods and the practical use of Computational Materials Science using two distinct examples: the development of optimized or alternative materials for CIGS (Copper-Indium-Gallium-di-Selenide) photovoltaics and the optimization of CIGS thin film solar cells for maximum efficiency. After a general introduction the theoretical background of the book is illustrated: The strategies and principles of High Performance Computing (HPC) for materials science are covered and rounded out by a number of examples for highly parallel computing. Next theory and working principles of solar cells are depicted with emphasis on CIGS. Finally the theory of the quantum mechanical simulations (Density Functional Theory, Monte Carlo simulations for canonical and grand-canonical ensembles, cluster expansions) and the software used for these purposes are presented. In the practical section of the book the simulation work for the various functional layers of the CIGS cell is described in detail: After general electronic structure calculations for the CIGS photo absorber light is shed on the role of the Indium/Gallium distribution as well as on the influence of vacancies in chalcopyrite structures. Base requirements for the buffer layer are defined and simulation results from a search for alternative (Cadmium-free) buffer compounds are presented. Experimental results for synthesized replacement materials complete this part of the work. The optimization of the system transparent conductive oxide (TCO) / contact grid for maximum overall cell efficiency is described. The charge transport through TCO/grid is modelled by a Finite Element Method and cell efficiencies are calculated considering ohmic as well as optical losses. The last section of the book outlines the simulation results implications on the optimization of thin film cell processing. Special emphasis is placed on the influence of process temperatures on film homogeneity and cell efficiency as well as on the requirements for substrate selection. The calculations are validated by experimental results.

Book Synopsis Modeling and Control of Thin Film Surface Morphology by : Jianqiao Huang
Download or read book Modeling and Control of Thin Film Surface Morphology written by Jianqiao Huang and published by . This book was released on 2012 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thin film solar cells, which consist of multiple layers such as the PIN layers and the Transparent Conducting Oxide (TCO) layers, are playing a more and more important role in the overall solar cell market owing to the potential of improving light conversion efficiencies (currently on the order of 10$\%$ for production modules). Over the last decade, it has been widely recognized that the surface morphology at each interface, which is characterized by surface root-mean-square roughness and slope, has crucial influence on the light conversion efficiency of thin film solar cells. Therefore, precisely shaping the surface morphologies of different layers in thin film solar cells during the thin film deposition process is a promising way to improve solar cell efficiency. Despite its importance, the computational modeling and control of the surface morphology, especially of the root-mean-square surface mean slope, during the thin film deposition process and its application to improve solar cell performance have not received enough attention. This dissertation presents a systematic framework for modeling and control of thin film surface morphology in both PIN layers and TCO layers. Specifically, we will present novel definitions for describing surface morphology by introducing both the surface root mean square roughness and slope to describe the surface morphology, study its physical properties and dependence on model parameters such like lattice size, activation energies and temperature, introduce and identify stochastic closed-form equations describing surface morphology, and finally design model predictive controllers to control the surface morphology to desired levels. Extensive simulation results are presented to demonstrate the effectiveness of the proposed modeling and control framework.

Book Synopsis Scanning Probe Microscopy Study of Thin Film Solar Cells by : Huan Li (Ph. D.)
Download or read book Scanning Probe Microscopy Study of Thin Film Solar Cells written by Huan Li (Ph. D.) and published by . This book was released on 2014 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thin film solar cells, such as CdTe, CuIn [subscript x] Ga [subscript 1-x] Se2 (CIGS), Cu2ZnSnS4 (CZTS) and Cu2ZnSnSe4 (CZTSe), have been intensively studied for their unique features and excellent prospect of mass production in industry. The p-n junction is the most critical part of the thin film solar cell and greatly influences the performance. In this thesis work, the p-n junctions and the device layers of multiple kinds of thin film solar cells have been studied by using scanning probe microscopy based techniques. The scanning spreading resistance microscopy (SSRM) has been developed on the cross-section of CdTe solar cells to study the resistance and carrier concentration distribution in different layers of the device. The CdTe sample was cleaved and milled with the argon ion beam to get a flat cross-section. The multiple device layers of the device were identified by the resistance mapping. A high-resistance region around the junction on the CdTe side due to carrier depletion was measured. With the AFM laser illumination, the resistance in the deep depletion region dropped and the resistance across the entire CdTe layer became relatively uniform due to domination of photo-excited carriers. With carriers injected by applying a forward-bias voltage to the working device, the resistance in the deep depletion region decreased and the region moved toward the CdS/CdTe interface. These observed trends and observations are consistent with device physics. We also measured the surface potential and the electric field across the junction using scanning Kelvin probe force microscopy (SKPFM) in the cross-section of the standard CIGS, ZnS(O,OH)/CIGS and the standard CZTSe devices. Both the heterojunction and homojunction situations of the three solar cells were simulated using the PC1D software. The simulation results were compared with the experimental results to analyze the properties of the junction. The comparison results provided the possible ranges of the thickness and carrier concentration of n-CIGS/n-CZTSe layer.

Book Synopsis Photovoltaic Modeling Handbook by : Monika Freunek Muller
Download or read book Photovoltaic Modeling Handbook written by Monika Freunek Muller and published by John Wiley & Sons. This book was released on 2018-08-03 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the reader with a solid understanding of the fundamental modeling of photovoltaic devices. After the material independent limit of photovoltaic conversion, the readers are introduced to the most well-known theory of "classical" silicon modeling. Based on this, for each of the most important PV materials, their performance under different conditions is modeled. This book also covers different modeling approaches, from very fundamental theoretic investigations to applied numeric simulations based on experimental values. The book concludes wth a chapter on the influence of spectral variations. The information is supported by providing the names of simulation software and basic literature to the field. The information in the book gives the user specific application with a solid background in hand, to judge which materials could be appropriate as well as realistic expectations of the performance the devices could achieve.
