Abstract

The properties of an indium-tin-oxide (ITO)/CdTe solar cell fabricated by spraying an alcoholic solution of indium chloride and tin chloride on n-type single crystal CdTe, have been investigated by measuring the electrical and photoelectrical properties of the device. The maximum sensitivity of the cells in the visible range attains 0.42 A/W. The efficiency of the solar cells without antireflection coating at AM1 condition is 6.2%. Detailed numerical calculations have been made for the effect of interface state density and localized charges in the interfacial layer on the performance of the cell.
