Characterization of rapidly thermally annealed Cu doped ZnTe thin films
CdTe solar cells can be produced inexpensively and Cu doped ZnTe films are used as back-contact interfacial layers for CdTe because they are p-type and have a small valence band discontinuity with CdTe1, which can improve grain quality and reduce defects. This research demonstrated that RTP annealing can improve device performance. A better understanding of the electrical effects of RTP annealing could lead to further enhanced cells. Glass slides were cut and cleaned for use as substrates. Thin films of Cu doped ZnTe were then deposited on each substrate in a vapor transport depositor. The ZnTe ...
