摘要:

半透明有机太阳能电池(STOSC)能够同时发电和透光, 是极具应用前景的新能源技术, 未来可应用于建筑物的窗户和屋顶实现光电建筑一体化, 以及农业温室和交通工具等多种领域. 然而, 半透明电池的能量转换效率(PCE)和平均可见光透过率(AVT)的均衡调谐仍是一个问题. 理想的高性能半透明有机太阳能电池需要平衡与提高AVT和PCE, 即在选择性吸收和利用非可见光谱的光子转换为电能的同时, 透过可见光谱区域光子实现透光, 并保持良好的审美观感和颜色纯度. 本文从活性层调控策略、 器件工程和多功能STOSC等多个角度, 讨论和总结了实现高性能STOSC的途径, 为推进该技术的研究和发展提供有益的参考和建议.

Abstract:

Semitransparent organic solar cells(STOSCs), capable of generating electricity and transmitting light simultaneously, are a highly promising new energy technology with potential applications in building-integrated photovoltaics for windows and roofs, as well as in agricultural greenhouses and transportation vehicles. However, the balance between the power conversion efficiency(PCE) and average visible light transmittance(AVT) of STOSCs remains a challenge. Ideal high-performance STOSC requires a balance between increasing the AVT and PCE, which involves selectively absorbing and utilizing non-visible spectrum photons for energy conversion while transmitting visible spectrum photons to maintain aesthetic appeal and color purity. In this review, we discuss and summarize various approaches to achieving high-performance STOSC from the perspectives of active layer tuning strategy, device engineering and multifunctional STOSCs. Our findings provide valuable insights and recommendations to promote the research and development of this promising energy technology.
