Rapid progress in the power conversion efficiency (PCE) of polymer solar cells (PSEs) is beneficial from the factors that match the irradiated solar spectrum, maximize incident light absorption, and reduce photogenerated charge recombination. To optimize the device efficiency, a nanopatterned ZnO:Al2O3 composite film is presented as an efficient light‐ and charge‐manipulation layer (LCML). The Al2O3 shells on the ZnO nanoparticles offer the passivation effect that allows optimal electron collection by suppressing charge‐recombination loss. Both the increased refractive index and the patterned deterministic aperiodic nanostructure in the ZnO:Al2O3 LCML cause broadband light harvesting. Highly efficient single‐junction PSCs for different binary blends are obtained with a peak external quantum efficiency of up to 90%, showing certified PCEs of 9.69% and 13.03% for a fullerene blend of PTB7:PC71BM and a nonfullerene blend, FTAZ:IDIC, respectively. Because of the substantial increase in efficiency, this method unlocks the full potential of the ZnO:Al2O3 LCML toward future photovoltaic applications.

具有90％外部量子效率的聚合物太阳能电池，具有理想的光和电荷操纵层
聚合物太阳能电池（PSE）的功率转换效率（PCE）的快速进步得益于与辐照太阳光谱匹配，最大化入射光吸收并减少光生电荷复合的因素。为了优化器件效率，提出了一种纳米图案的ZnO：Al 2 O 3复合膜作为有效的光和电荷控制层（LCML）。ZnO纳米颗粒上的Al 2 O 3壳具有钝化作用，可通过抑制电荷复合损失来实现最佳电子收集。ZnO：Al 2 O 3的增加的折射率和图案化的确定性非周期性纳米结构LCML导致宽带光收集。获得了用于不同二元共混物的高效单结PSC，峰值外部量子效率高达90％，对于PTB7：PC 71 BM富勒烯共混物和FTAZ非富勒烯共混物，经认证的PCE分别为9.69％和13.03％。IDIC，分别。由于效率的大幅提高，该方法为未来的光伏应用释放了ZnO：Al 2 O 3 LCML的全部潜力。
