In the present study, the performance improvement of the promising eco-friendly Cu₂ZnSnS₄ (CZTS) solar cells have been investigated numerically using Al plasmonic nanoparticles. The optical and electrical simulations were performed using the finite-difference time-domain (FDTD) method. It was revealed that loading plasmonic nanoparticles on the topmost layer of the CZTS solar cell leads to light absorption enhancement in the cell. By sweeping the radius of plasmonic nanoparticles from 20 nm to 60 nm, a significant enhancement in the efficiency occurred. The variation of the external quantum efficiency (EQE) and photovoltaic current density–voltage (J–V) curve under air mass of AM1.5 with and without plasmonic nanoparticles were also studied.

在本研究中，已经使用Al等离子体纳米颗粒对数值化的有前景的环保Cu ₂ ZnSnS ₄（CZTS）太阳能电池的性能进行了研究。使用有限差分时域（FDTD）方法进行光学和电气仿真。揭示了在CZTS太阳能电池的最上层上加载等离激元纳米颗粒导致电池中光吸收的增强。通过将等离子纳米粒子的半径从20 nm扫描到60 nm，可以显着提高效率。外部量子效率（EQE）和光伏电流密度-电压（J – V）的变化还研究了在有和没有等离激元纳米粒子的情况下，在AM1.5空气质量下的曲线。
