Fabrication of High Efficiency CdTe Thin Film Solar Cells Using Electrodeposition

Research output: Contribution to conference › Paper

Abstract

The influences of CdTe and CdS film thicknesses and CdS pre-treatment on CdTe solar cell performances were investigated. The CdTe film thickness was varied from 2.2 to 5.3 .mu.m. The CdS film thickness was varied from 700 .ANG. to 2500 .ANG. The highest efficiencies were obtained with a CdTe thickness of 3.4 .mu.m and a CdS thickness of 1500 .ANG. An increase of 2.7 mA/cm/sup 2/ in J/sub sc/ wasobserved as a result of CdC/sub 2/ treatment of CdS, resulting from an improved spectral response in the wavelength range of 500-600 nm. CdCl/sub 2/ treatment of CdS affects CdTe-CdS interdiffusion and leads to differences in optical transmission of CdS films. X-ray diffraction studies indicated the full conversion of CdS into CdS/sub 1-y/TE/sub y/ ternary phase for films prepared withas-deposited CdS and very low concentration of CdS/sub 1-y/Te/sub y/ for films prepared with CdCl/sub 2/-treated CdS.
