铜蒸发温度对共蒸发法制备Cu2ZnSnSe4太阳电池的影响
Effect of Copper Evaporation Temperature on the Performance of Cu2ZnSnSe4 Thin Film Solar Cells Prepared by Co-evaporation Process
摘要
Abstract
To know well the effect of Cu concentration on the performance of of Cu2ZnSnSe4 (CZTSe) thin film solar cells.CZTSe thin film solar cells prepared at different Cu evaporation temperature was investigated.The results indicate that the low TCu(1400 ℃) cause additional reflections of secondary phase SnSe and the films are N-type conduction.The quality of crystallization of CZTSe films is improved with increasing TCu.But the secondary phase of CuxSey is observed for CZTSe films deposited at TCu of 1500 ℃.Both secondary phase of SnSe and CuxSey could cause devices electrically inactive.The best solar cell with an efficiency of 2.63% is obtained at medium TCu of 1450 ℃ (active area 0.34 cm2).关键词
