Unified upper bound for photothermal and photovoltaic conversion efficiency
Journal of Applied Physics, 2008The available work (exergy) of thermal radiation is derived ab initio by using a simple statistical thermodynamic approach. A general upper bound for the efficiency of thermal radiation conversion into work is derived. This efficiency is different from the Carnot efficiency and generalizes the Petela efficiencylike factor appearing in the available ...

Evaluation of exergy and energy efficiencies of photothermal solar radiation conversion
Applied Solar Energy, 2009In this paper, a new thermodynamic model for photothermal solar radiation conversion into mechanical through a heat engines is proposed. The developed equations allow for the energy and exergy contents of solar radiation to be found, as well as the energy and exergy efficiencies corresponding to concentration type solar-thermal heat engines operating ...

Efficient Hybrid Photovoltaic-Photothermal Solar Conversion System With Cogeneration
SPIE Proceedings, 1985A new type of concentrating photovoltaic-photothermal solar conversion system with output cogeneration is presented. This technique, called total solar cogeneration (TSC), converts the total solar spectrum directly and cogenerates the output into three energy components: high-temperature heat (HT), photovoltaic electricity (PV), and low-temperature ...
