Abstract

A metalorganic selenide, diethylselenide [(C2H5) 2Se: DESe], was used as a less-hazardous selenization source for the preparation of CuInGaSe2 alloy films for solar cell application. Purely single-phase, polycrystalline films of CuInGaSe2 were formed without additional annealing process. Photoluminescence spectra of the films at low temperature were dominated by three donor-acceptor pair emissions peculiar to the films used for a photo-absorbing layer of state-of-the-art CuInGaSe 2-based solar cells.
