Figure 6From: CZTSe solar cells prepared by electrodeposition of Cu/Sn/Zn stack layer followed by selenization at low Se pressureThe X-ray diffraction spectrum of CZTSe thin films that are prepared under three selenization conditions. (a) Without a tin source (A1), (b) with a tin source at 400°C (A2), and (c) with a tin source at 530°C (A3).Back to article page
