摘要

中文摘要: 在CdTe与金属背电极间形成稳定的低电阻接触，有助于提高CdTe太阳电池性能。采用硝酸-冰乙酸腐蚀CdTe薄膜并用真空蒸发法沉积铜背接触层，制备CdTe太阳电池。结果表明，化学腐蚀后在膜面生成了富碲层，硝酸-冰乙酸腐蚀为各向同性刻蚀。对背接触层进行优化退火处理，获得转化效率11.75%的CdTe太阳电池。

Abstract

Abstract:Forming a low resistance contact to CdTe thin films is a key issue for successful improvement of the performance of CdTe solar cells. The CdTe thin films were etched with nitric-acetic (NA) acid and a Cu back contact layer was deposited onto the etched CdTe surface

then the CdTe solar cells were fabricated. The results indicated that the nitric acetic acid pretreatment forms a highly conductive Te layer on the back surface of the CdTe thin films and it is an isotropic etching. An efficiency of 11.75% for CdTe solar cells was obtained when the back contact layer was annealed under optimum conditions.
