This report provides a method to estimate how much the photocurrents can be increased by adding gold nanoparticles in P3HT:PCBM films, without having to carry out the complex process of fabricate a whole cell. The tuning effect of varying the gold nanoparticle concentration on optical properties of these films was analyzed by measuring optical absorption. To estimate the contribution of the optical absorption variation, theoretical photocurrents generated for these films as active layers were calculated using a photonic flux density equation. With this methodology, it is possible to estimate the amount of energy that can be harvest with a given gold nanoparticle concentration. Improvements up to 26% were obtained compared with films without added gold nanoparticles.

P3HT:PCBM:Au 薄膜的光电流增强估计与金纳米粒子浓度的函数关系

该报告提供了一种方法来估计通过在 P3HT:PCBM 薄膜中添加金纳米粒子可以增加多少光电流，而无需执行制造整个电池的复杂过程。通过测量光吸收来分析改变金纳米粒子浓度对这些薄膜的光学特性的调谐效果。为了估计光吸收变化的贡献，使用光子通量密度方程计算这些薄膜作为活性层产生的理论光电流。使用这种方法，可以估计在给定的金纳米颗粒浓度下可以收获的能量量。与未添加金纳米颗粒的薄膜相比，性能提高了 26%。
