Abstract Semitransparent (ST) organic photovoltaics (OPVs) are demonstrating great potential for building integration applications, especially in windows. For that purpose, ST-OPVs should achieve adequate transparency and performance stability. In this regard, the present research deals with the experimental performance of three different building-integrated ST-OPV technologies (technology A: developed in the frame of the present study; technologies B and C: commercial modules). More specifically, spectral transmittance and electrical measurements have been conducted in order to determine the characteristics of the modules for building integration and electricity generation purposes. Results regarding the transmittance reveal that technology A outperforms technologies B and C. The stability analysis of the modules verifies that module C is the most stable one with almost no decrease (3.6%) in the power conversion efficiency (PCE). Furthermore, the PCE of technology B is slightly higher than in the case of technology C, which experiences a PCE degradation of about 10–15% over the whole time period. Finally, technology A presents a 20% reduction in PCE at around 500 h.

用于建筑集成的半透明 OPV 的性能和稳定性:基准分析

摘要 半透明 (ST) 有机光伏 (OPV) 在建筑集成应用中展现出巨大的潜力,尤其是在窗户方面。为此,ST-OPV 应达到足够的透明度和性能稳定性。在这方面,本研究涉及三种不同的建筑集成 ST-OPV 技术(技术 A:在本研究框架内开发;技术 B 和 C:商业模块)的实验性能。更具体地说,已经进行了光谱透射率和电气测量,以确定用于建筑集成和发电目的的模块的特性。关于透射率的结果表明,技术 A 优于技术 B 和 C。模块稳定性分析证实,模块C是最稳定的模块,功率转换效率(PCE)几乎没有下降(3.6%)。此外,技术 B 的 PCE 略高于技术 C,技术 C 在整个时间段内经历了约 10-15% 的 PCE 降级。最后,技术 A 在大约 500 小时时将 PCE 降低了 20%。
