摘要:

我们计算了有机太阳能电池中激子的短路扩散电流,特别强调了荧光损失。激子扩散长度是不均匀的,但随着其在器件内的位置而变化,即使具有中等的荧光量子效率。在量子效率较大的情况下,通过适当选择几何参数和介电参数,可以大大降低荧光率。通过这种方式,可以增加扩散长度并且显著改善器件性能。

英文摘要:

We compute the short-circuit diffusion current of excitons in an organic solar cell, with special emphasis on fluorescence losses. The exciton diffusion length is not uniform but varies with its position within the device, even with moderate fluorescence quantum efficiency. With large quantum efficiencies, the rate of fluorescence can be strongly reduced with proper choices of the geometrical and dielectric parameters. In this way, the diffusion length can be increased and the device performance significantly improved.
