Abstract
Control of the initial stage of the CdTe deposition was investigated by mod ifying the substrate and the source temperature profiles in close-spaced su blimation (CSS) process for improving the performance of CdTe thin film sol ar cells. In the modified temperature profile, the substrate temperature wa s increased with higher rate than that of the source temperature. By using the modified temperature profile, the conversion efficiency was improved as compared with the conventional temperature profile, and 15.3% efficiency( V-oc:0.811 V, J(sc): 26.3 mA/cm(2), FF: 0.718, 1 cm(2), AM 1.5) was achieve d.
