Photoconductivity and photovoltaic effect in indium selenide
Transport and phototransport properties of crystalline indium monoselenide (InSe) doped with a variety of elements are reported. Measured mobilities, lifetimes, and effective diffusion lengths of photoexcited carriers are used to interpret electrical and photovoltaic properties of several different structures. These include pân junctions, bismuth/pâtype InSe, platinum/nâtype InSe, and indium tin oxyde (ITO)/pâtype InSe. External solar efficiencies of the best devices are between 5% and 6%. The influence on the efficiency of the various parameters is evaluated, and ways of improvement are discussed
