Abstract

Cu(In,Ga)Se₂ (CIGS) solar cell junctions prepared by chemical-bath-deposited (CBD) ZnS(O,OH), Zn-Cd-S(O,OH), and CdS buffer layers are discussed in this paper. The device performances are compared by applying CBD ZnS(O,OH), CBD Zn-Cd-S(O,OH), and CBD CdS buffer layers on similar CIGS absorbers. The CN impurities in CBD ZnS(O,OH) are identified with Fourier transform infrared spectroscopy (FTIR) techniques. The impurities containing carbon-nitrogen bonds are most likely cyanamide (NCN^2-) or thiocyanate (SCN^-), which resulted from the chemical reaction of thiourea and ammonia.
