Properties of the thin-film solar cells with heterojunctions Cusub2/subS-Cdsub1/sub-subx/subZnsubx/subS and Cusub2/subSe-Cdsub1/sub-subx/subZnsubx/subSe

摘要

In recent years, resumed intensive studies of heterojunctions, in connection with the possibility of using them on the most economical and relatively efficient photodetectors. In this economy is determined by the structure of production technology and the value of the source material. Thus there is a substitution reaction on the surface of the films Cdsub1-x/subZnsubx/subS formed a second layer of Cusub2/subS, whose thickness is determined by the time of deposition. When light 1,45?10sup4/sup lux photocells studied Cusub2/subS-Cdsub1-x/subZnsubx/subS and Cusub2/subSe-Cdsub1-x/subZnsubx/subSe generated voltage 0,5÷0,6V and in 0,45-0,58V, current Jsubsc/sub 15 ÷ 20 mA/smsup2/sup and 12-15mA/cmsup2/sup and efficiency were = 11%. and 8%. respectively. It is established that with increasing content of Zn in the base material-circuit voltage Usubos/sub photocell increases and short-circuit current decreases. Using as a base material of solid solutions of Cdsub1-x/subZnsubx/subS and Cdsub1-x/subZnsubx/subSe causes an increase in the potential barrier at the contact.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
