This book was released on 2021-08-24 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thin-film solar cells are cheap and easy to manufacture but require improvements as their efficiencies are low compared to that of the commercially dominant crystalline-silicon solar cells. An optoelectronic model is formulated and implemented along with the differential evolution algorithm to assess the efficacy of grading the bandgap of the CIGS, CZTSSe, and AlGaAs photon-absorbing layer for optimizing the power-conversion efficiency of thin-film CIGS, CZTSSe, and AlGaAs solar cells, respectively, in the two-terminal single-junction format. Each thin-film solar cell is modeled as a photonic device as well as an electronic device. Solar cells with two (or more) photon-absorbing layers can also be handled using the optolelectronic model, whose results will stimulate experimental techniques for bandgap grading to enable ubiquitous small-scale harnessing of solar energy.

This book was released on 2014-04-23 with total page 893 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook is a compendium giving a comprehensive description of the basics of semiconductor physics relevant to the design and analysis of thin film solar cell materials. It starts from the basics of material science, describing the material and its growth, defect and electrical properties, the basics of its interaction with photons and the involved statistics, proceeding to space charge effects in semiconductors and pn-junctions. Most attention is given to analyze homo- and hetero-junction solar cells using various models and applying the field-of-direction analysis for discussing current voltage characteristics, and helping to discover the involvement of high-field effects in solar cells. The comprehensive coverage of the main topics of - and relating to - solar cells with extensive reference to literature helps scientists and engineers at all levels to reach a better understanding and improvement of solar cell properties and their production. The author is one of the founders of thin film solar cell research.
Download or read book A Novel Approach to Modeling the Effects of Radiation in Gallium Arsenide Solar Cells Using Silvaco s ATLAS Software written by Aaron L. Crespin and published by . This book was released on 2004-09-01 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of radiation in GaAs solar cells has been extensively researched and the results of numerous investigation have yielded a considerable amount of information about the degradation in irradiated solar cells. This thesis establishes a novel method in which to use Silvaco's physically-based device simulator, ATLAS, to model the effects of radiation on solar cell output characteristics. A virtual model representing a single junction GaAs solar cell was created in ATLAS. The effects of radiation were modeled using carrier trapping statements representing the defects associated with various fluence levels of 1 MeV electron radiation which were characterized with Deep Level Transient Spectroscopy techniques. The resulting output characteristics of the virtual solar cell, illuminated with a simulated AM0 spectrum, were compared to published experimental measurements for GaAs solar cells of the same dimensions. The virtual solar cell demonstrated a good correlation between the measured and virtual solar cell output characteristics and accurate representation of the spectral response. Complete ATLAS and MATLAB codes are included in appendices.
Download or read book The Physics of Solar Cells written by Juan Bisquert and published by CRC Press. This book was released on 2017-11-15 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides an explanation of the operation of photovoltaic devices from a broad perspective that embraces a variety of materials concepts, from nanostructured and highly disordered organic materials, to highly efficient devices such as the lead halide perovskite solar cells. The book establishes from the beginning a simple but very rich model of a solar cell, in order to develop and understand step by step the photovoltaic operation according to fundamental physical properties and constraints. It emphasizes the aspects pertaining to the functioning of a solar cell and the determination of limiting efficiencies of energy conversion. The final chapters of the book establish a more refined and realistic treatment of the many factors that determine the actual performance of experimental devices: transport gradients, interfacial recombination, optical losses and so forth. The book finishes with a short review of additional important aspects of solar energy conversion, such as the photonic aspects of spectral modification, and the direct conversion of solar photons to chemical fuel via electrochemical reactions.

This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Modeling and process optimization of solar cell devices is a complex procedure due to the high-dimensional parameter space. Moreover, the need for enhancing renewable energy market share is an undeniable fact. Machine learning is rapidly emerging in many fields while providing a promising toolbox for researchers to study complex problems more efficiently. Traditionally, research in materials science has involved a trial-and-error process that often requires various resources. With the help of machine learning, we can explore the high-dimensional problems with improved accuracy and efficiency and fewer user-imposed assumptions.This thesis presents the modeling and sensitivity analysis of GaAs-based (Gallium arsenide-based) solar cell device processes. We propose a unifying framework for learning a solar cell performance function while providing intuitive interpretations based on the sensitivity analysis of the cell performance with respect to the material variables. In fact, this framework would be a faster and more computationally efficient replacement for its equivalent simulator in a downstream task of sensitivity analysis and consequently design optimization. We use the conditional variational autoencoder and multilayer perceptron for the generative modeling task and Jacobian-based sensitivity indices for the sensitivity analysis task. Furthermore, in the results, we validate our modeling approach with a baseline multilayer perceptron and our sensitivity analysis method with a sampling-based sensitivity analysis approach. We further demonstrate how the sensitivity analysis can be potentially useful from the design perspective as well as interpretability of possible device underperformance"--

This book was released on 1976 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pressure pulses caused by irradiation of a model gallium arsenide solar cell with a Carbon Dioxide TEA Laser were examined using power densities of the order of 10 to the 7th power watts/sq cm. The pressure pulses were monitored with a Sandia type quartz pressure gauge. It was discovered that the relatively low power densities used were capable of removing the silicon dioxide antireflective and gold contact layers of the solar cell after only a few shots of the laser. An exponential relationship between the initial thicknesses of these layers and the pressure pulse generated in the gallium arsenide substrate was indicated for gold contact layers of less than 5000 A thickness. Evidence was found that the principal pressure generation mechanism is thermo-mechanical. Gold films of thickness greater than 5000 A were found to be able to absorb the power densities used with no apparent damage. (Author).

This book was released on 2012 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Gallium Arsenide solar cells are of particular interest in many applications due to its advantages over silicon. Its high absorptivity requires a cell that is only few microns thick, compared to silicon. GaAs cells are relatively insensitive to heat and their resistance to radiation also makes the GaAs based cell preferable to Si for extra-terrestrial applications. In this research, the effects of front and bottom texturing on the GaAs solar cell were studied, in particular their effects on the fill factor, open circuit voltage and the short circuit currents were analyzed. Silvaco, an industry standard simulation suite was used for the design and analysis of the various texturing for the GaAs solar cell. In this thesis, five different cell models consisting of the un-textured cell, top, bottom, top and bottom, as well as meta-structures were considered for analysis. Using AM1.5 spectrum with the aid of beam parameter of the simulation software under 1-sun condition, Isc and Voc were obtained. The IV characteristics were plotted for all the models in the presence and absence of light, providing light and dark currents for the cell. Maximum power generated in the device was measured and the Fill Factor calculated. The texturing's were considered on the window layer and above the gold mirror layer for top and bottom texturing's respectively, with In0.5Ga0.5P and also with a combination of alternating metal dielectric slabs forming a meta structure over a gold layer on the window layer. Results for these designs showed that the performance of various GaAs solar cells with In0.5Ga0.5P texturing on the top has better device characteristics compared to other designs.
