Thin-film solar cell with a thermoelectric layer

One of the economically viable solutions of the thin-film solar cell on the basis of: the photoelectric converter, based on CuInSe$_2$-CdS, and the thermoelectric layer, based on CuInSe$_2$, is considered in this paper. This construction of the solar cell is implemented in the COMSOL Multiphysics software package. During the simulation, conditions close to operational conditions were taken into account. The temperature patterns and the temperature gradient patterns of the solar cell are obtained by using numerical methods. The use of the thermoelectric layer, the solar radiation concentration as well as maintenance of the operating temperature of the photoelectric converter due to the temperature stabilization of the substrate back side made it possible to achieve an increase in the output power of the solar cell up to 5%.
