摘　　要：对低温化学浴沉积方法制备的Zn(O,S)薄膜进行了研究,通过XPS、SEM、XRD、拉曼光谱、PL谱、紫外-可见吸收光谱等手段对薄膜的形貌、结构及组成进行系统表征,探究了其作为钙钛矿电池电子传输层的可能性。研究表明:化学浴沉积(CBD)方法制备的Zn(O,S)薄膜为ZnO、Zn S和ZnOS合金的复合膜;该薄膜对CH_3NH_3Pb I3光吸收层具有与TiO_2相当的电子抽提能力,是一种可供选择的高效柔性钙钛矿电池电子传输层材料。Zn(O,S)thin film has been successfully used in Cu(In,Ga)Se2 based solar cells.However,its application in perovskite solar cell has not been reported.In this paper,Zn(O,S)film prepared by low temperature chemical bath deposition has been studied.The morphology,structure and composition of the film were characterized by XPS,SEM,XRD,Raman spectra,PL spectra and UV-Visible absorption spectra.The band structure of the thin film is analyzed by UPS.The possibility of Zn(O,S)film being the electron transport layer of the perovskite solar cell is explored.The research shows that the Zn(O,S)thin film deposited by CBD belongs to the mixed membrane.The composition of the phase consists of ZnO,ZnS and ZnOS alloys.The prepared Zn(O,S)film has the equivalent electronic extraction capability to the CH3NH3PbI3 optical absorption layer with TiO2.It is a kind of high efficient flexible perovskite battery electronic transport layer material.
