1. Introduction Over the last thirty years, there has been an important growth in clean energy production and renewable energy generation. To this end, a considerable number of studies examined hybrid energy systems, i.e., systems that combine multiple types of energy generation. In 1997, Rozakis et al. [1] carried out a study on hybrid energy systems, combining different technologies: wind power generation, micro-hydraulic unit and biomass generator. The study by Rozakis et al.

Summary Operating a solar cell under thermal stress at temperatures >100°C and up to 500°C seems counterintuitive because conversion efficiency drops dramatically. Even so, there are cases in which solar cells are in high-illumination high-temperature conditions, for near-the-sun space missions and in various terrestrial hybrid systems involving solar-to-thermal energy conversion. This review analyzes the progress of solar cells tested in the laboratory under thermal stress.
