Solar Energy Harvesting: How to Generate Thermal and Electric Power Simultaneously
PDF ISBN: 9781510604940 | Print ISBN: 9781510604957
This Spotlight describes energy harvesting using a hybrid concentrating photovoltaic (PV) system with simultaneous thermal generation for energy storage. Several designs have been proposed to build a system that takes advantage of the entire solar spectrum through direct electric generation using concentrated light onto photovoltaics while generating thermal energy using wavelengths of light not captured by the PV cell. This eBook addresses the current technologies and state-of-the-art designs, as well as the methodologies, underlying physics, and engineering implications.
This Spotlight was motivated by the growing interest in so-called hybrid solar energy systems, ones which can co-generate electricity and medium-to-high temperature thermal energy simultaneously. In the United States much of the interest was generated by the ARPAE FOCUS funding program which supported many of the projects discussed within, but outside the US significant research is being undertaken in this area particularly in Australia, China, and India. The goal of our book is to inform readers about basic considerations within photovoltaics and solar thermal collectors, including levelized costs, since these form the basis for the hybrid systems. Further discussion is included on spectrum-splitting approaches, selective filtration approaches, optical design, and issues in thermal packaging. Detailed discussion is provided on the role of nanoparticles as spectrally selective absorbers as well.
