Available in PDF, EPUB and Kindle. Book excerpt: In terms of efficiency, perovskite solar cells have seen the most fastest increase in efficiency. While it took silicon over a decade to reach 20\% efficiency, perovskite cells reached similar efficiencies in a matter of years (\cite{NRELchart}), making them the fastest advancing solar technology in history. We will primarily focus on recent advancements in perovskite luminescent solar concentrators (LSCs) with the theoretically optimal values for perovskite LSCs of various compositions and thickness. The Monte-Carlo simulation framework used to study the effectiveness of luminescent solar concentrators (LSCs) will be established in detail. We use a similar framework to that established by \cite{Sahin} for semiconductor nanoparticles. Computational efficiency is improved through implementation of a vectorized Monte Carlo simulation method. Perovskite LSCs are compared against previously used CdSe-CdTe quantum dots. We thereby establish perovskite as a viable, highly efficient LSC as published by \cite{Ghosh} and obtain ideal perovskite composition and thickness for optimal perovskite LSC performance as published by \cite{Boe}. The other part of this thesis implements a deterministic ray tracing algorithm combined with appropriate optimization methods to evaluate the performance of segmented non-imaging solar thermal concentrators. Under user-specified parameters and constraints, new concentrator configurations are obtained which optimize theoretical efficiency. Such configurations have not yet been discussed in literature. Pattern search, a gradient free optimization method, is employed to determine ideal segment positions. The presence of numerous local minima make gradient-based optimization solvers ineffective.

Book excerpt: A limited pilot production run on PESC silicon solar cells for use at high concentrations (200 to 400 suns) is summarized. The front contact design of the cells was modified for operation without prismatic covers. The original objective of the contract was to systematically complete a process consolidation phase, in which all the, process improvements developed during the contract would be combined in a pilot production run. This pilot run was going to provide, a basis for estimating cell costs when produced at high throughput. Because of DOE funding limitations, the Photovoltaic Concentrator Initiative is on hold, and Applied Solar's contract was operated at a low level of effort for most of 1993. The results obtained from the reduced scope pilot run showed the effects of discontinuous process optimization and characterization. However, the run provided valuable insight into the technical areas that can be optimized to achieve the original goals of the contract.

This book was released on 2013 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystalline silicon solar cells are a proven renewable energy technology, but they have yet to reach low costs commensurate with subsidy-free, grid-scale adoption. To achieve the widespread adoption of photovoltaics, the cost per unit of electricity must be reduced by increasing solar cell efficiency. Parts per trillion concentrations of iron impurities in the silicon material can severely limit solar cell efficiency. Iron can be found in both precipitated and point defect form in silicon. Both forms are detrimental to final solar cell efficiency, but their negative impact can be mitigated during solar cell processing. In a standard solar cell process, the phosphorus diffusion step is the key opportunity to redistribute iron impurities because it is the step with the largest thermal budget. Phosphorus diffusion process optimization for solar cell material so far typically consists of one or more isothermal steps followed by a cooling step. Iron silicide precipitates can be dissolved at high temperatures, whereas at lower temperatures, interstitially dissolved iron is driven to the phosphorus-rich layer. Previous optimizations typically maximize minority carrier lifetime without constraining process time and device parameters. This thesis explores a novel phosphorus diffusion process in which there are no isothermal steps. The goal of this work is to demonstrate simultaneous maximization of minority-carrier lifetime, while maintaining high process throughput and steady emitter sheet resistance. Predictive simulation, electrical characterization techniques, and synchrotron-based X-ray fluorescence were combined to compare this new processing approach to standard solar cell processing. This continuously ramped temperature processing may be a promising approach for maximizing solar cell performance, maintaining reasonable manufacturing rates, and achieving a target sheet resistance.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to provide a comprehensive overview of the fundamentals and engineering of high concentrator photovoltaic (HCPV) technology and to elucidate how this complex and emerging technology is applied in power plants. It is the first of its kind to focus exclusively on HCPV technology and offers a valuable reference volume to readers. This book is the result of an international collaboration among experts and each chapter is written by a specialist in the field. The conversion of solar energy to electricity plays an important role in power generation and HCPV is signalled by many researchers and professionals as one of the most promising sources of solar power. Therefore this book provides an important resource for companies, research institutes and universities to assist with the understanding of fundamentals, different applications and potential of such technology.
