A tri-metallic nano-particles (NPs) involving Silver, Iron and Nickel (Ag:Fe:Ni) was successfully synthesized using a wet chemical reduction method. The synthesized nano-composite (Ag:Fe:Ni) has exhibited polycrystalline morphology in powder form, which was used as nano-composite in a P3HT:PCBM blend solar absorber layer of the thin film organic solar cell (TFOSC) to enhance the collection of photons. Consequently, the power conversion efficiency (PCE) of the thin film organic solar cells grew by 42% due to the incorporation of NPs in the devices structure. However, the concentration of metal nano-particles was varied from 0% to 3% by weight to determine the optimum doping level of the NPs for maximum effect in the solar absorbers. The effect of the metal nano-particles is clearly evident by high short circuit current ($J_{sc}$) of TFOSC which is attributed to improve the dissociation of exciton and charge transport processes in the medium. The optical and morphological characteristics of the nanoparticles were discussed in terms of the measured parameters.

使用湿化学还原法成功合成了一种涉及银、铁和镍 (Ag:Fe:Ni) 的三金属纳米粒子 (NPs)。合成的纳米复合材料 (Ag:Fe:Ni) 以粉末形式呈现多晶形态，用作薄膜有机太阳能电池 (TFOSC) 的 P3HT:PCBM 混合太阳能吸收层中的纳米复合材料，以增强收集的光子。因此，由于在器件结构中加入了 NP，薄膜有机太阳能电池的功率转换效率 (PCE) 提高了 42%。然而，金属纳米颗粒的浓度从 0% 到 3% 重量变化，以确定纳米颗粒的最佳掺杂水平，以在太阳能吸收器中发挥最大作用。金属纳米粒子的效果在高短路电流下很明显（$J_{秒C}$) 的 TFOSC，这归因于改善介质中激子和电荷传输过程的离解。根据测量参数讨论了纳米颗粒的光学和形态特征。
