CuCl Doping Variations in High Efficiency Polycrystalline CdSeTe/CdTe Thin Film Solar Cells

Abstract

In this paper, the influence of CuCl doping process parameters on the performance of solar cells was studied. The devices were fabricated with graded CdSeTe/CdTe absorber. The critical parameters for CuCl doping process were identified and varied in a 2-level 3-factor statistically designed experiment. The analysis of response data generated from the performance of the devices was analyzed using JMP software. The performances of devices with 19%+ revealed two different optimal processing conditions for CuCl doping.
