Plasmonic metal electrodes with subwavelength nanostructures are promising for enhancing light harvesting in photovoltaics. However, the nonradiative damping of surface plasmon polaritons (SPPs) during coupling with sunlight results in the conversion of the excited hot-electrons to heat, which limits the absorption of light and generation of photocurrent. Herein, an energy recycling strategy driven by hot-electron emission for recycling the SPP energy trapped in the plasmonic electrodes is proposed. A transparent silver-based plasmonic metal electrode (A-PME) with a periodic hexagonal nanopore array is constructed, which is combined with a luminescent organic emitter for radiative recombination of the injected hot-electrons. Owing to the suppressed SPP energy loss via broadband hot-electron emission, the A-PME achieves an optimized optical transmission with an average transmittance of over 80% from 380 to 1200 nm. Moreover, the indium-tin-oxide-free organic solar cells yield an enhanced light harvesting with a power conversion efficiency of 16.1%.

有机太阳能电池透明等离子体电极中的热电子发射驱动能量回收
具有亚波长纳米结构的等离子体金属电极有望用于增强光伏器件的光收集。然而，表面等离子体激元（SPPs）在与太阳光耦合过程中的非辐射阻尼导致激发的热电子转化为热量，从而限制了光的吸收和光电流的产生。在此，提出了一种由热电子发射驱动的能量回收策略，用于回收捕获在等离子体电极中的 SPP 能量。构建了具有周期性六边形纳米孔阵列的透明银基等离子体金属电极（A-PME），该电极与发光有机发射器相结合，用于对注入的热电子进行辐射复合。由于通过宽带热电子发射抑制 SPP 能量损失，A-PME 实现了优化的光学传输，在 380 到 1200 nm 范围内的平均透射率超过 80%。此外，不含氧化铟锡的有机太阳能电池产生增强的光收集，功率转换效率为 16.1%。
