我们通过在有机太阳能电池(OSCs)中使用周期性波纹金属电极来提高OSCs的效率。效率的提高可以归因于波纹金属/有机界面上传播的表面等离子激元(SPP)模的激发导致吸收的增强。通过将SPP共振调谐到本征吸收区，适当周期的波纹器件的短路电流从平面器件的4.1 mA/cm2提高到5.5 mA/cm2。功率转换效率提高了35%。
We demonstrate improved efficiency of organic solar cells (OSCs) by employing a periodically corrugated metallic electrode in the OSCs. The improved efficiency can be attributed to the absorption enhancement resulted from the excitation of propagating surface-plasmon polariton (SPP) modes at the corrugated metal/organic interface. Through tuning the SPP resonance to the intrinsic absorption region, the short circuit current of the corrugated device with appropriate period has been increased from 4.1 mA/cm2 for planar device to 5.5 mA/cm2. The power conversion efficiency exhibits an enhancement of 35%.
