为提高有机太阳能电池(OSCs)的能量转换效率
将蛾眼微结构应用于OSCs上。通过理论模拟计算
得出在有机层厚度一定的情况下
带有蛾眼微结构的OSCs相比于普通平板结构的OSCs的光吸收效率有较大的提高。通过对微结构形貌、周期和高度的优化
使蛾眼结构OSCs的光吸收效率比普通平板OSCs提高了11.3%。器件光场分布的模拟计算表明
光吸收效率的提高是由蛾眼结构减反增透的效果和表面等离子体(SPP)增强吸收共同导致的结果。
In order to improve the energy conversion efficiency of organic solar cells (OSCs)
the moth-eye structure was applied to OSCs. According to the theoretical simulation
in a certain active layer thickness
the moth-eye OSCs has a large enhancement in light absorption efficiency compared with the planar OSCs. Through the optimization of microstructure morphology
period and height
the moth-eye OSCs has an increase of 11.3% in light absorption efficiency than the planar OSCs. The simulation of the distribution of magnetic field intensity in the moth-eye OSCs indicates that the light absorption enhancement can be attributed to both the anti-reflective effect of moth-eye structures and the enhanced absorption effect of the surface plasmon polariton (SPP).
