Stability of CdTe solar cell prepared with rapid-thermal processed ZnTe:Cu back contacts and different metallizations
This research examines the stability of CdTe cells prepared with rapid-thermal processed ZnTe:Cu back contacts. Two degradation sets were performed in this work. In the first set, CdTe cells with different window layers; CdS (standard device) and alloy CdS1−yTey (alloy device) were dark stressed at 85⁰C. The alloy devices has an additional high resistive transparent (HRT) layer between the transparent conducting oxide (TCO) and the alloy. The second set studies the degradation of standard CdTe devices with different back contact metallization (Au and Ti) under thermal stressing at 75 and ...
