Abstract

Ditertiarybutylsulfide [(t-C 4H 9) 2S: DtBS] was shown to be a promising, less hazardous alternative source for the sulfurization of CuInS 2 films. Single-phase, polycrystalline CuInS 2 films were formed at 575°C for 15 min. Photoluminescence spectra at low temperatures were dominated by characteristic bands at 1.34 and 1.37 eV, demonstrating that the films are a suitable material for the photo-absorbing layer of CuInS 2-based solar cells. These results represent the first step toward realizing a solar cell using a CuInS 2 film grown by sulfurization using an organometallic source and conventional, large-scale equipment.
