| Abstract: | CdTe thin films were etched with a mixture of nitric-phosphoric acid(NP)in water.A dilute solution of bromine in methanol(BM)was also applied to CdTe thin films for comparison.The effects of NP acid and BM pretreatments on the material properties were investigated.Then four back contact materials were deposited on the CdTe thin films etched with two surface pretreatments.A novel back-contact technique was proposed.Furthermore,two CdTe solar cells with high performance back contacts were measured from C-V measurements and analyzed using energy band structure. |
