One of the most crucial considerations for practical applications of Organic Photovoltaics (OPV) is the stability under sunlight irradiation. It is necessary to translate the small device stability to the module level. Herein, the photostability of the OPV module with three cells connected in series with a total effective area of 10.8 cm2 is presented. The stability of the OPV module is studied under continuous irradiation by a UV light‐emitting diode (LED) with integrated UV intensity the same as AM1.5 solar irradiations. As a result, the OPV module achieved good stability under UV light with a half‐lifetime of about 1300h without a UV filter. The lifetime is similar to the small device with the same materials. The serious resistance and the encapsulation must be optimized simultaneously. The suitable metal of the external electrode greatly improves the OPV module’s performance. In addition, the UV stability of the normal structure is shown to be better than the inverted structure because of the photo instability of the ZnO layer. Moreover, the UV stability of semitransparent OPV modules is shown to be‐ similar to the opaque ones.This article is protected by copyright. All rights reserved.

紫外线照射下具有良好稳定性的有机太阳能组件

有机光伏（OPV）实际应用最重要的考虑因素之一是阳光照射下的稳定性。有必要将小型器件的稳定性转化为模块级别。其中，总有效面积为10.8 cm的三片电池串联的OPV组件的光稳定性2被呈现。研究了 OPV 模块在 UV 发光二极管 (LED) 连续照射下的稳定性，其综合 UV 强度与 AM1.5 太阳辐射相同。结果，OPV组件在紫外光下实现了良好的稳定性，在没有紫外滤光片的情况下半衰期约为1300小时。寿命与相同材料的小型设备相似。严重的电阻和封装必须同时优化。合适的外部电极金属极大地提高了OPV组件的性能。此外，由于ZnO层的光不稳定性，正常结构的紫外稳定性优于倒置结构。此外，半透明 OPV 组件的紫外线稳定性与不透明组件相似。本文受版权保护。版权所有。
