The localized surface plasmon resonance (LSPR) effects of nanoparticles (NPs) are effective for enhancing the power conversion efficiency (PCE) of organic solar cells (OSCs). In this study, spiky durian-shaped Au@Ag core-shell NPs were synthesized and embedded in the hole transport layer (HTL) (poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS)) of PTB7:PCBM bulk-heterojunction OSCs. Different volume ratios of PEDOT:PSS-to-Au@Ag NPs (8%, 10%, 12%, 14%, and 16%) were prepared to optimize synthesis conditions for increased efficiency. The size properties and surface morphology of the NPs and HTL were analyzed using field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and atomic force microscopy (AFM). UV-Vis spectroscopy and current density-voltage (J-V) analysis were used to investigate the electrical performance of the fabricated OSCs. From the results, we observed that the OSC with a volume ratio of 14% (PEDOT:PSS-to-Au@Ag NPs) performed better than others, where the PCE was improved from 2.50% to 4.15%, which is a 66% increase compared to the device without NPs.
纳米粒子（NPs）的局域表面等离子体共振（LSPR）效应可有效提高有机太阳能电池（OSCs）的功率转换效率（PCE）。在本研究中，合成了带刺榴莲形状的Au@Ag核壳纳米粒子，并将其嵌入PTB7:PCBM体异质结有机太阳能电池的空穴传输层（HTL）（聚（3,4-乙撑二氧噻吩）：聚（苯乙烯磺酸盐）（PEDOT:PSS））中。制备了不同体积比的PEDOT:PSS与Au@Ag纳米粒子（8%、10%、12%、14%和16%），以优化合成条件来提高效率。使用场发射扫描电子显微镜（FESEM）、透射电子显微镜（TEM）和原子力显微镜（AFM）分析了纳米粒子和空穴传输层的尺寸特性及表面形态。利用紫外可见光谱和电流密度-电压（J-V）分析来研究所制备有机太阳能电池的电学性能。从结果中我们观察到，体积比为14%（PEDOT:PSS与Au@Ag纳米粒子之比）的有机太阳能电池性能优于其他电池，其功率转换效率从2.50%提高到了4.15%，与不含纳米粒子的器件相比提高了66%。
