Abstract
Crystals of the compound In2S3 were grown by planar crystallization of the melt. The composition, structure, and electrical characteristics of the crystals obtained were determined. Photosensitive structures based on the grown In2S3 crystals were fabricated for the first time; spectral dependences of photoconversion quantum efficiency for H2O/In2S3 cells were measured. The features of the band-to-band absorption are discussed; energies of the direct and indirect optical transitions for In2S3 crystals are estimated. It is stated that In2S3 crystals can be used in wide-range (1.5–3.5 eV) photoconverters of nonpolarized radiation (in particular, in solar cells).
