Here we demonstrate a promising flat-panel solar thermal to electric power conversion technology based on the Seebeck effect and high thermal concentration, thus enabling wider applications. The developed solar thermoelectric generators (STEGs) achieved a peak efficiency of 4.6% under AM1.5G (1 kW m −2) conditions.
Conventional wisdom is that thermoelectrics are most suitable for waste heat recovery and that materials with significantly higher ZT are needed for large-scale applications 7, 22, 23. We will show that thermoelectrics are an attractive alternative for converting solar energy into electricity.
