چکیده: (99 مشاهده)
Advancements in light-based technologies necessitate the development of optoelectronic devices for future renewable energy applications. A key challenge in enhancing the efficiency of organic solar cells (OSCs) lies in improving light absorption in the near-infrared (NIR) region, where conventional organic materials, such as P3HT:PCBM, suffer from inherently weak absorption. In this study, we introduce a hexagonal periodic array of aluminum (Al) nanocylinders as a low-cost and effective plasmonic platform to address this limitation. Using finite-difference time-domain (FDTD) simulations, we optimized the nanostructure embedded within the P3HT:PCBM active layer. The proposed design excites strong localized surface plasmon resonances (LSPRs), leading to a significant enhancement in near-field intensity and effective optical path length, particularly across the 650–1200 nm spectrum. Through systematic optimization of nanocylinder dimensions (height: 50 nm, radius: 15 nm) and array periodicity (21 nm), an optimal active layer thickness of 150 nm was identified. The resulting plasmonic OSC achieves a short-circuit current density ( 
) of 36.04 
, twice the value compared to a reference cell without nanoparticles. These results underscore the promising role of aluminum nanocylinders in enabling high-performance, thin-film, and cost-effective photovoltaic devices.
