In this paper a modified design of a solar Parabolic Trough Thermoelectric Receiver (PTTR) tube is presented and its technical feasibility is evaluated theoretically. The innovative driving concept is its cylindrical tri-segmented receiver tube coupled with a thermoelectric generator (TEG). The system is analyzed numerically for a set of operation and design parameters and the results are discussed. This work opens up a promising option which has the potential to improve the conversion of solar thermal energy into electricity through parabolic trough system. We also explored the possibility of multi-component energy conversion using the modified structure.read more

Analysis and optimization of the low-temperature solar organic Rankine cycle (ORC)
TL;DR: In this article, the authors considered the case in which the thermal energy required by a solar ORC is supplied by means of stationary solar collectors and derived the operating conditions of the ORC that minimizes the aperture area needed per unit of mechanical power output for every working fluid and every solar collector.
