本文报道了沉积在氟掺杂氧化锡（FTO）玻璃衬底上的银纳米颗粒耦合石墨烯薄膜的等离子体激元增强光传输。建立了一个实验装置，以量化由于金属纳米颗粒嵌入石墨烯层的光子增强。结果表明，石墨烯纳米片在银纳米颗粒沉积的FTO玻璃上的特定分布可以捕获光伏应用的最大垂直入射光。对于沉积在FTO/Ag（3 nm）上的30 μL石墨烯分散体，观察到硅太阳能电池（保持在Ag涂覆的FTO玻璃下）的电流密度提高6.35%。结果表明，通过将金属纳米颗粒的等离子体激元振荡与石墨烯等离子体激元相结合来最小化入射辐射的反射的可能性，这可以用于光电器件、辐射传感器和各种类型的光伏电池。
This paper reports plasmon-enhanced light transmission through the Ag nanoparticle-coupled graphene thin-film deposited on fluorine-doped tin oxide (FTO) glass substrates. An experimental set-up is developed to quantify the photon enhancement due to metal nanoparticle-embedded graphene layer. The results show that a specific distribution of graphene nanosheets over Ag nanoparticle-deposited FTO glass can trap maximum normally incident light for photovoltaic applications. An enhancement of 6.35 % in the current density of silicon solar cell (kept under Ag-coated FTO glass) is observed for 30-μL graphene dispersion deposited on the FTO/Ag (3 nm). The results indicate the possibility of minimizing the reflection of incident radiation by combining plasmonic oscillations of metal nanoparticles with graphene plasmonics, which can be useful for optoelectronic devices, radiation sensors, and various types of photovoltaic cells.
