Controlling the characteristics of photovoltaic cells based on their own semiconductors

Abstract

The features of photovoltaic cells with their own photoconductivity in semiconductors with deep-level multiply-charge impurity have been considered. The use of such structures can significantly extend the dynamic range of sensitivity and gain new functional properties of single-element photoelectric receivers. Photovoltaic converters based on semiconductors with deep-level multiply-charge acceptor type impurity enable devices with a wider functionality, whereas the structure with multiply-charge donor type impurity has better linearity of energy performance. In the development of photoelectric receiver with advanced functionality features the model of recombination processes in multiply-charge impurity in a wide range of optical radiation power density has been used.
