我们报告通过将 (Au:Ag) 纳米粒子 (NP) 嵌入有机太阳能电池的 P3HT:PCBM 活性层来提高有机太阳能电池的功率转换效率。此外，还研究了氯苯和氯仿溶剂对 P3HT:PCBM 活性层的影响进行比较。众所周知，基于区域规则性 P3HT:PCBM 共混物的有机太阳能电池的性能很大程度上受共混物组成的影响。为此，制备了ITO/PEDOT:PSS/P3HT:PCBM/(Au:Ag) NPs/LiF/Al四元混合太阳能电池。对用氯苯（CB）和氯仿（CF）溶剂制备的四元氢化物活性层进行了吸收、AFM、SEM 和 XRD 测量。计算了混合活性层的光学能带隙。 1.2% Au:0.3% AgNPs 比例获得最高 PCE 值，研究重点关注这些值。有源层中的 (Au:Ag) NP 将使用 CB 和 CF 溶剂制备的器件的功率转换效率 (PCE) 分别从 2.11% 提高到 3.29% 和 2.27%。这种增加的原因是来自纳米粒子的入射光的散射以及太阳能电池活性层中光吸收的增强，从而增加了光路距离。
We report to enhance the power conversion efficiency of organic solar cells by embedding of (Au:Ag) nanoparticles (NPs) into P3HT:PCBM active layer of the organic solar cells. Furthermore, the effect of solvents based on chlorobenzene and chloroform on the P3HT:PCBM active layer has been investigated for comparison. As known, the performance of organic solar cells based on the blend of regioregular P3HT:PCBM is strongly influenced by blend composition. For this purpose, ITO/PEDOT:PSS/P3HT:PCBM/(Au: Ag) NPs/LiF/Al quaternary hybrid solar cells were fabricated. Absorption, AFM, SEM and XRD measurements of the quaternary hydride active layers prepared with chlorobenzene (CB) and chloroform(CF) solvents were obtained. The optical energy band gap of the hybrid active layer was calculated. The highest PCE values were obtained for 1.2% Au:0.3% AgNPs ratios and the study has been focused on these values. (Au:Ag) NPs in the active layer increased the power conversion efficiency (PCE) of the device from 2.11% to 3.29% and to 2.27% for prepared with CB and CF solvents, respectively. This increase was explained by the scatter of the incident light from the NPs and an enhancement of light absorption in the active layer of the solar cell, increasing the optical path distance.
