Abstract

In this paper, electrical properties CdS/CdTe heterojunction solar cell prepared by electron beam evaporation method were investigated. Crystal structure of CdS films deposited at substrate temperature of $50{\sim}250^{\circ}C$ was hexagonal type with preferential orientation of the (002)plane parallel to the substrate. Optical transmittance of the CdS film is increasing and resistivity is decreasing with increasing subsrate temperature. CdS/CdTe Solar cell characteristics were improved by increasing of substrate and annealing temperature. However, low efficiency due to small Jsc, Voc below 0.3 $mA/cm^2$ and 430 mV are observed. Low efficiency is contributed to be high resistance of CdTe films and contact.
