Summary / Abstract: Installation environments of solar cells are surrounded by heat, which are also exhausted from the cells themselves and degrade the device performance normally. Here we report an experiment to show that hybrid devices of silicon solar cells and commercial thermoelectric materials, bismuth telluride, can recover heat to exhibit a positive temperature characteristic, i.e., the output power increases with the solar cell temperature. The result implies the hybrid structure can be another type of realization for our concept of “heat recovery solar cell”, namely the type II (HERC-II).
