Influence of pulse reversal on the performance of pulse electrodeposited copper indium sulphide solar cells

摘要

This paper reports for the first time influence of pulse reversal on the properties and performance of pulse electrodeposited CuInS_2 films. The films exhibited single phase chalcopyrite structure. The intensity of the X-ray diffraction peaks become sharp and increase in intensity with increase of pulse reversal time. The crystallite size increases with pulse reversal time. Resistivity of the films decreases from 2.0 to 0.05 Ω cm with increase of pulse reversal time. The mobility and carrier density increase with pulse reversal time. Solar cells fabricated with Mo/ CuInS_2/CdS/Ag have yielded reasonable photo outputs.
