Chemical Bath Deposition of Antimony Selenosulfi de Thin Films and the Photovoltaic Performance of the Corresponding Solar Cells

利用酒石酸锑钾、硫代硫酸钠、硒代硫酸钠作为锑、硫、硒源,通过化学浴法成功制备了硒硫化锑(Sb_(2) S_(3-y)Se_(y))薄膜,组装了结构为FTO/CdS/Sb_(2) S_(3-y)Se_(y)/spiro-OMeTAD/Au的太阳电池,系统研究了化学浴生长时间对所得Sb_(2) S_(3-y)Se_(y)薄膜的微结构、晶相、光学吸收及其相应太阳电池光伏性能的影响。结果表明,当生长时间为5h、7h、9h时,所得Sb_(2) S_(3-y)Se_(y)薄膜的厚度为70nm、100nm、110nm,相应太阳电池的光电转换效率为5.27%、5.66%、5.64%。

Antmony selenosulfde(Sb_(2)S_(3-y)Se_(y))thn flms were successfully prepared by chemcal bath deposton(CBD)usng antmony potass-um tartrate,sodum thosulfate and sodum selenosulfate as sources of antmony,sulfur and selenum.The solar cells wth the archtecture of FTO/CdS/Sb_(2)S_(3-y)Se_(y)/spro-OMeTAD/Au were fabrcated.The influence of CBD growth tme on the mcrostructure,crystallne phase,optcal absorpton of Sb_(2)S_(3-y)Se_(y) thn flms and the photovoltac performance of the correspondng solar cells was systematcallynvestgated.When the growth time of CBD was 5 h,7 h,9 h,the thickness of Sb_(2)S_(3-y)Se_(y) thn flms was 70 nm,100 nm,110 nm,and the power conversion efficiency of the corresponding solar cells was 5.27%,5.66%,5.64%.
