摘要
采用磁控溅射法制备出透明导电氧化物NiO薄膜.椭偏(SE)测试表明NiO薄膜在可见光区域透光性良好,通过调节生长、退火温度可调控NiO的折射率.采用X射线衍射(XRD)、扫描电子显微镜(SEM)手段研究表明,通过退火、改变衬底温度等,可有效改变Ni薄膜的晶体结构以及表面形貌,实现对NiO导电性的调控.采用优化后的NiO材料为阳极阻挡层制备出的聚合物太阳能电池器件的效率为2.26%,是同等条件下采用PEDOT:PSS阻挡层的电池器件的3倍以上.
NiO films are prepared with radio frequency magnetron sputtering.Ellipsometric experiment results show that NiO film is transparent for visible light.and its refractive index can be modified by changing T_（sub） and annealing temperature.Scanning electron microscopy and X-ray diffraction experiment results show that T_（sub） and annealing temperature can modify the morphology and crystal structure of NiO film which can further modify the conductivity of NiO.The optimized NiO film is used in polymer solar cell（PSC） as an anode blocking layer.The experimental results show that NiO is a better candidate than the PEDOT：PSS often used as an anode blocking layer for PSC.The power conversion efficiency of PSC with NiO reaches 2.26%which is three times as high as that with PEDOT.PSS.
