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.

This book was released on 2019 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concentrating solar power (CSP) with thermal energy storage has the potential for grid-scale dispatchable power generation. Thermochemical energy storage (TCES), that is, the reversible conversion of solar-thermal energy to chemical energy, has high energy density and low heat loss over long periods. In this work, we develop optimization-based models for the design and analysis of CSP with different fluid-phase and solid-gas TCES systems. By proposing various TCES process strategies, evaluating their system performance, and identifying key areas of improvement, we hope that our study will help accelerate TCES development and solar power deployment. Specifically, we first develop a general process model for CSP plants employing fluid-phase TCES systems. We illustrate our model applicability by using ammonia and methane TCES systems. The analysis allows us to identify pressure vessels for aboveground gas storage as the main cost driver and compressor electricity consumption as the main energy driver. The overall energetic and economic performance can be significantly improved if cheap underground gas storage is available. We then propose an optimization-based framework for process synthesis under variability in two frequencies. We introduce scenarios and modes to represent low and high frequency variability respectively, and formulate the synthesis problem as a multimode two-stage stochastic programming model. The proposed approach is well suited to address the synthesis of renewable energy systems where the energy resource (e.g., solar, wind) often exhibits variability in two scales. Next, we develop an optimization model for the design and operation of CSP plants employing solid-gas TCES systems. Special emphasis is placed on the modeling of fixed-bed reactors that operate in a cyclic batch mode, which are modeled using partial differential equations in time and space. Finally, we provide a system-level analysis for CSP employing various solid-gas TCES strategies, that is, different combinations of chemical reactions and process configurations. Six process configurations are proposed and three types (carbonate, hydroxide, and redox) of reactions are studied. Results show that, six out of the nine strategies have the potential to improve energy efficiency and reduce costs at the same time over two-tank molten salt storage. We also analyze the impacts of key reaction properties and process parameters on system performance.

Download or read book Geometric Optimization of Solar Concentrating Collectors Using Quasi Monte Carlo Simulation written by Andrew James Marston and published by . This book was released on 2010 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is a study of the geometric design of solar concentrating collectors. In this work, a numerical optimization methodology was developed and applied to various problems in linear solar concentrator design, in order to examine overall optimization success as well as the effect of various strategies for improving computational efficiency. Optimization is performed with the goal of identifying the concentrator geometry that results in the greatest fraction of incoming solar radiation absorbed at the receiver surface, for a given collector configuration. Surfaces are parametrically represented in two-dimensions, and objective function evaluations are performed using various Monte Carlo ray-tracing techniques. Design optimization is performed using a gradient-based search scheme, with the gradient approximated through finite-difference estimation and updates based on the direction of steepest-descent. The developed geometric optimization methodology was found to perform with mixed success for the given test problems. In general, in every case a significant improvement in performance was achieved over that of the initial design guess, however, in certain cases, the quality of the identified optimal geometry depended on the quality of the initial guess. It was found that, through the use of randomized quasi-Monte Carlo, instead of traditional Monte Carlo, overall computational time to converge is reduced significantly, with times typically reduced by a factor of four to six for problems assuming perfect optics, and by a factor of about 2.5 for problems assuming realistic optical properties. It was concluded that the application of numerical optimization to the design of solar concentrating collectors merits additional research, especially given the improvements possible through quasi-Monte Carlo techniques.

This book was released on 2016-11-10 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: After decades of research and development, concentrating solar thermal (CST) power plants (also known as concentrating solar power (CSP) and as Solar Thermal Electricity or STE systems) are now starting to be widely commercialized. Indeed, the IEA predicts that by 2050, with sufficient support over ten percent of global electricity could be produced by concentrating solar thermal power plants. However, CSP plants are just but one of the many possible applications of CST systems. Advances in Concentrating Solar Thermal Research and Technology provides detailed information on the latest advances in CST systems research and technology. It promotes a deep understanding of the challenges the different CST technologies are confronted with, of the research that is taking place worldwide to address those challenges, and of the impact that the innovation that this research is fostering could have on the emergence of new CST components and concepts. It is anticipated that these developments will substantially increase the cost-competiveness of commercial CST solutions and reshape the technological landscape of both CST technologies and the CST industry. After an introductory chapter, the next three parts of the book focus on key CST plant components, from mirrors and receivers to thermal storage. The final two parts of the book address operation and control and innovative CST system concepts. Contains authoritative reviews of CST research taking place around the world Discusses the impact this research is fostering on the emergence of new CST components and concepts that will substantially increase the cost-competitiveness of CST power Covers both major CST plant components and system-wide issues
