Abstract

Thin films of CdS were prepared from an solution containing Cd(Ac)2, NH4OH, NH4Ac and (NH2)2CS for solar cells. Growth rate of CdS films was increased with increasing temperature of reactive solution and with decreasing concentration of NH4OH. Optical transmittances were more than 60% independent with temperature and concentrations and was changed with thickness of CdS films. Grown films mostly showed the presence of polycrystallines with mixed cubic and hexagonal phases, but showed the hexagonal preferred phases in some growth condition. The resistivities of CdS were decreased by doping boron from 104 to 101 order(Ω - cm) and the critical amount of dopant was 5 × 10− .mol %
