空穴传输层是有机光伏器件中的重要组成部分。本文制备了一种可用于空穴传输层的高分子复合膜, 制备过程采用了静电自组装(LbL)的方式和低温常压的还原条件。相比于其他制备方式, 本文提出的方法不仅厚度可控而且具有更好的电学性能。实验中采用紫外-可见光吸光光度计(UV-Vis spectrometer)对结果进行验证。实验表明, 低温常压条件下的还原结果与传统的高温真空条件得到的结果非常接近。低温条件减少了对高分子链的破坏, 使得复合膜的空穴迁移率可以由10-6 cm2/Vs提升到10-5 cm2/Vs的数量级。

Hole conduction layer is one of the most important part in organic solar cells. In this study, we prepare a macromolecular composite film suitable for hole conduction in an organic solar cell using layer-by-layer (LbL) deposition technique and low conversion temperature process under ambient conditions. As opposed to previous processes, our method not only supplies a controllable layer thickness but also provides a better electric property. An UV-Vis spectrometer is used to verify our results. It shows that low temperature conversion process under ambient condition works just the same as traditional high temperature conversion process under vacuum conditions. Low-temperature conversion process causes fewer damages on the structure of the macromolecule and raises hole mobility from 10-6 cm2/Vs to around 10-5 cm2/Vs.
