We studied the effect of gold quantum dots (AuQDs)/grating-coupled surface plasmon resonance (GC-SPR) in inverted organic solar cells (OSCs). AuQDs are located within a GC-SPR evanescent field in inverted OSCs, indicating an interaction between GC-SPR and AuQDs' quantum effects, subsequently giving rise to improvement in the performance of inverted OSCs. The fabricated solar cell device comprises an ITO/TiO₂/P3HT : PCBM/PEDOT : PSS : AuQD/silver grating structure. The AuQDs were loaded into a hole transport layer (PEDOT : PSS) of the inverted OSCs to increase absorption in the near-ultraviolet (UV) light region and to emit visible light into the neighbouring photoactive layer, thereby achieving light-harvesting improvement of the device. The grating structures were fabricated on P3HT:PCBM layers using a nanoimprinting technique to induce GC-SPR within the inverted OSCs. The AuQDs incorporated within the strongly enhanced GC-SPR evanescent electric field on metallic nanostructures in the inverted OSCs improved the short-circuit current and the efficiency of photovoltaic devices. In comparison with the reference OSC and OSCs with only green AuQDs or only metallic grating, the developed device indicates enhancement of up to 16% power conversion efficiency. This indicates that our light management approach allows for greater light utilization of the OSCs because of the synergistic effect of G-AuQDs and GC-SPR.

我们研究了倒置有机太阳能电池（OSC）中金量子点（AuQDs）/光栅耦合表面等离子体激元共振（GC-SPR）的影响。AuQD位于倒置OSC中的GC-SPR渐逝场内，表明GC-SPR和AuQD的量子效应之间存在相互作用，从而提高了倒置OSC的性能。所制造的太阳能电池装置包括ITO / TiO ₂/ P3HT：PCBM / PEDOT：PSS：AuQD /银光栅结构。将AuQD加载到倒置OSC的空穴传输层（PEDOT：PSS）中，以增加在近紫外（UV）光区域的吸收并将可见光发射到相邻的光敏层中，从而实现对光敏层的光收集改进。设备。光栅结构是使用纳米压印技术在P3HT：PCBM层上制造的，以在反向OSC内诱导GC-SPR。倒置OSC中金属纳米结构上强烈增强的GC-SPR渐逝电场中包含的AuQD改善了短路电流和光伏装置的效率。与仅具有绿色AuQD或仅具有金属光栅的参考OSC和OSC相比，开发的设备表明功率转换效率最高可提高16％。这表明由于G-AuQD和GC-SPR的协同作用，我们的光管理方法可提高OSC的光利用率。
