Solution‐Grown Cadmium Sulfide Films for Photovoltaic Devices

Thin films of cadmium sulfide have major applications in optoelectronic devices. Several techniques have been developed for the deposition of films. Among these, growth of films from an aqueous solution is the low‐cost technique suitable for many applications. In this work, the deposition of device quality films on glass and substrates from an aqueous solution containing cadmium acetate, ammonia, ammonium acetate, and thiourea has been investigated. The structural and electrical properties of films have been characterized. The doping of films with boron and the properties of boron‐doped films have also been studied. High efficiency thin film solar cells have been prepared from solution‐grown films.
