Polymer photovoltaics have become a promising alternative energy due to lightweight properties, environmental friendliness, and solution processability. Transparent organic photovoltaics in particular have been recently receiving more attention in the photovoltaics field due to their unique potential in future applications beyond mere harvesting of solar energy. This perspective is further enhanced by the recent developments of high-performance polymer photovoltaics (including infrared absorbing materials and devices) that could achieve superior visible transparency and power conversion efficiency. To realize high-performance transparent organic photovoltaics, the main strategy is to shift the active-layer absorption spectrum to the infrared region by designing new low-bandgap donors and non-fullerene acceptors, and to reduce the invalid absorption by developing new transparent electrode materials. The potential applications are diverse, especially for spectrum-sensitive ones such as the greenhouse in agriculture. Finally, some key research areas of transparent organic photovoltaics that may deserve further attention are discussed.

由于重量轻，环境友好和溶液可加工性，聚合物光伏已成为一种有前途的替代能源。特别是透明有机光伏材料，由于其在未来的应用领域中不仅具有太阳能的收获潜力，还因其在未来应用中的独特潜力，最近在光伏领域受到了越来越多的关注。高性能聚合物光伏（包括红外吸收材料和设备）的最新发展进一步增强了这种观点，该聚合物光伏可以实现卓越的可见透明性和功率转换效率。为了实现高性能的透明有机光伏电池，主要策略是通过设计新的低带隙供体和非富勒烯受体，将有源层吸收光谱转移到红外区域，通过开发新的透明电极材料来减少无效吸收。潜在的应用是多种多样的，尤其是对光谱敏感的应用，例如农业温室。最后，讨论了一些可能值得进一步关注的透明有机光伏的关键研究领域。
