介绍了一种高功函数的掺杂钛酸镧的氧化铟透明导电阳极并用其制备了有机光伏器件,详细研究了该材料对器件性能的影响,同时对比了ITO为阳极的器件性能。由于ILTO具有较好的掺杂、较高的透过率和高的有效表面功函数等优异的光电特性,与基于ITO的器件相比,ILTO的有机光伏器件的填充因子、短路电流及功率转换效率均得到了优化与提升,填充因子由61.1%提高到63.5%,短路电流由3.26 mA/cm2提高到5.64 mA/cm2,功率转换效率由0.91%提高到1.45%。
A high work function lanthanum titanate doped indium oxide transparent conducting anode was prepared and used to prepare the organic photovoltaic device. The influence of the material on the performance of the device was studied in detail. Meanwhile, the device performance of ITO was compared. Due to the excellent optoelectronic properties of ILTO with better doping, higher transmittance and high effective surface work function, the fill factor, short-circuit current and power conversion of the ILTO organic photovoltaic device The efficiency is improved and the filling factor is increased from 61.1% to 63.5%, the short-circuit current is increased from 3.26 mA / cm2 to 5.64 mA / cm2, and the power conversion efficiency is increased from 0.91% to 1.45%.
