Organic photovoltaic (OPV) cells have exhibited great advantages for indoor applications. However, large energetic disorder restricts the performance of OPV cells under low illuminance, which brings significant challenges for indoor applications. Here, we demonstrate that concentrated indoor light can suppress the effects of energetic disorder and simultaneously enhance the open-circuit voltage and fill factor of OPV cells. Remarkably, PB2:FCC-Cl-based cells achieve a state-of-the-art PCE of 33.0% when concentrating indoor light to 20,000 lux. Meanwhile, all OPV cells exhibit superior stability under concentrated indoor light due to mild lighting conditions. Especially for the PBDB-TF:Y6 system exhibiting the best morphological stability, an extrapolated intrinsic lifetime is over 30,000 h. Combined with optical waveguide concentrators, we also reveal that concentrating OPV cells have the potential for low-cost manufacturing. These results suggest that developing concentrating OPV cells is quite necessary for indoor applications in the future.

有机光伏(OPV) 电池在室内应用方面表现出巨大优势。然而，大能量无序限制了OPV电池在低照度下的性能，这给室内应用带来了重大挑战。在这里，我们证明集中的室内光可以抑制能量紊乱的影响，同时提高 OPV 电池的开路电压和填充因子。值得注意的是，基于 PB2:FCC-Cl 的电池实现了最先进的PCE将室内光线集中到 20,000 勒克斯时，亮度为 33.0%。同时，由于光照条件温和，所有 OPV 电池在集中的室内光下都表现出优异的稳定性。特别是对于表现出最佳形态稳定性的 PBDB-TF:Y6 系统，外推的固有寿命超过 30,000 小时。结合光波导聚光器，我们还揭示了聚光 OPV 电池具有低成本制造的潜力。这些结果表明，开发聚光OPV电池对于未来的室内应用是非常必要的。
