The Chloride Annealing for Back Contact Layer Free CdTe Solar Cells

Abstract:

The large area CdTe thin film samples were used for chloride annealing. The CuCl₂/NH₄Cl solution was attached on the CdTe surface. After annealing treatment, the CdTe solar cells were prepared. The structure of the thin films and the properties of the CdTe solar cells were tested for studying the effect of the ratio of Cu/Cl, solution concentration and the annealing temperature. At last the performance of CuCl₂/NH₄Cl annealing cells, ZnTe back contact cells and C:Te,Cu back contact cells were compared. Without back contact layers the efficiency of the CdTe solar cells reached 11.13% with chloride annealing.
