电子显微镜已用于研究有机太阳能电池暴露在潮湿空气中时的降解。已经研究了具有常用有机太阳能电池空穴传输层和阴极材料的各种不同组合的器件。通过这种方式，可以研究水的进入及其对器械的影响。发现阴极中的钙和铝都与水反应，导致装置内的空隙和分层。发现使用聚（3，4-亚乙基二氧噻吩）聚苯乙烯磺酸盐（PEDOT：PSS）可通过缓解水进入器械而增加降解。更换这些材料消除了这些降解特征。版权所有© 2015作者.

Electron microscopy has been used to study the degradation of organic solar cells when exposed to humid air. Devices with various different combinations of commonly used organic solar cell hole transport layers and cathode materials have been investigated. In this way the ingress of water and the effect it has on devices could be studied. It was found that calcium and aluminum in the cathode both react with water, causing voids and delamination within the device. The use of poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) was found to increase the degradation by easing water ingress into the device. Replacing these materials removed these degradation features. © 2015 The Authors. Journal of Polymer Science Part B: Polymer Physics published by Wiley Periodicals, Inc. J. Polym.
