Thermophotovoltaic Properties of Bi2Te3 AND Bi2Se3

Abstract

Thermophotovoltaic properties monocrystals Bi2Te3 p-type and Bi2Se3 are investigated. P-n film structures of p-Bi2Te3–n-Bi2Se3, received by a method of discrete thermal evaporation in a uniform work cycle, are suitable for usage in thermophotovoltaic devices. It is demonstrated, that the wide spectrum of sensitivity and stability to the concentrated solar radiation of thermophotovoltaic elements on the basis of AVBVI are advantage in comparison with traditional solar cells. The modelling of concentrator solar cells with thermophotovoltaic converters is carried out in order to guide the technology to increase the performance of these devices.
