Plasmonic nanoparticles are promising ways for the efficiency enhancement of thin-film solar cells. We have taken into account the bare silicon wafer and the embedded thin-film silicon solar cells with Au nanodiscs array. We study these geometries of thin-film silicon solar cells and find the effect of Au nanoparticles on light transmission and reflection spectrum, power absorption, generation rate, power electric, and short-circuit current density; and for this, we have used finite difference time domain, FDTD software. We also consider the near-field electric intensity in the vicinity of nanoparticles with different sizes, which are known as a solar cells efficiency enhancement mechanism. Our study can be useful for new perspectives for antireflection coating applications and light management in silicon solar cells.

通过等离子体纳米盘阵列提高薄膜硅太阳能电池的效率

等离子体纳米粒子是提高薄膜太阳能电池效率的有前途的方法。我们已经考虑了裸硅晶片和带有 Au 纳米盘阵列的嵌入式薄膜硅太阳能电池。我们研究了薄膜硅太阳能电池的这些几何形状，并发现了 Au 纳米粒子对光透射和反射光谱、功率吸收、发电率、电力和短路电流密度的影响；为此，我们使用了时域有限差分 FDTD 软件。我们还考虑了不同尺寸纳米粒子附近的近场电场强度，这被称为太阳能电池效率增强机制。我们的研究可为硅太阳能电池中的抗反射涂层应用和光管理提供新的视角。
