Figure 4From: CZTSe solar cells prepared by electrodeposition of Cu/Sn/Zn stack layer followed by selenization at low Se pressureGibbs energy change of the reaction of Sn with Se x as the main reactant. The Gibbs energy change of the reaction of Sn with Se x (where x = 5, 6, 7) as the main reactant at a temperature of less than 550°C.Back to article page
