Abstract
Single-phase coarse-grained CuIn3Se5 ingots are grown by horizontal oriented crystallization from the near-stoichiometric melt. Photosensitive structures based on the interface between these crystals and an electrolyte (H2O) are created. It is shown that the CuIn3Se5 ternary compound is a direct-gap semiconductor with an energy gap Eg ≃ 1.1 eV (T = 300 K). H2O/CuIn3Se5 photoelectrochemical cells seem to be promising for efficient wide-band photodetectors of natural light.
