We demonstrate a facile approach to designing transparent electron-collecting electrodes by depositing thin layers of medium and low work function metals on top of transparent conductive metal oxides (TCOs) such as ITO and FTO. The modified electrodes were fairly stable for months under ambient conditions and maintained their electrical characteristics. XPS spectroscopy data strongly suggested integration of the deposited metal in the TCO structure resulting in additional doping of the conducting oxide at the interface. Kelvin probe microscopy measurements revealed a significant decrease in the ITO work function after modification. Organic solar cells based on three different conjugated polymers have demonstrated state of the art performances in inverted device geometry using Mg- or Yb-modified ITO as electron collecting electrode. The simplicity of the proposed approach and the excellent ambient stability of the modified ITO electrodes allows one to expect their wide utilization in research laboratories and electronic industry.

ITO改性，用于高效的反向有机太阳能电池

我们展示了一种设计透明电子收集电极的简便方法，该方法是在诸如ITO和FTO的透明导电金属氧化物（TCO）上沉积中等和低功函数金属的薄层。修饰的电极在环境条件下可稳定使用数月，并保持其电气特性。XPS光谱数据强烈建议将沉积的金属整合到TCO结构中，从而导致在界面处额外掺杂导电氧化物。开尔文探针显微镜测量显示，改性后ITO功函数显着降低。基于三种不同的共轭聚合物的有机太阳能电池已经证明了使用Mg或Yb改性的ITO作为电子收集电极在反向器件几何结构方面的最新技术性能。
