چکیده :
Renewable energy sources, particularly solar energy, hold great promise for meeting the global demand for electricity. Among the latest advancements in photovoltaic technology, perovskite-based solar cells have garnered significant attention due to their impressive performance and cost-effectiveness. However, single-junction perovskite solar cells face an inherent theoretical efficiency limit of 33%, as defined by the Shockley-Queisser limit. Bifacial solar cells are compelling solution for efficiency limitation of single-junction solar cells. These cells can capture sunlight from both their front and rear surfaces, potentially enhancing overall efficiency and stability. Unlike previous studies that relied on one-dimensional models for electrical calculations, this research employs comprehensive three-dimensional structural analyses for both optical and electrical evaluations. In this context, a meticulously designed and simulated three-dimensional bifacial perovskite solar cell has emerged. This Bi-PSC boasts high efficiency and minimal thickness, featuring a bandgap of 1.55 eV. Notably, it utilizes SnO₂ as the electron transport layer and MoO₃ as the hole transport layer. The simulations were carried out using the Finite Element Method, and various plasmonic metallic nanoparticles were evaluated to further enhance performance. Our research reveals that the strategic integration of plasmonic nanoparticles within the central region of the absorber layer, maintaining a symmetric structure, markedly improves the overall efficiency of the system under both front and rear irradiation. We observed a remarkable efficiency improvement of 40.55% (increasing from 17.95% to 25.23%) under front irradiation, as well as a significant 37% enhancement (rising from 17.55% to 24.04%) for rear irradiation. Furthermore, we attained a short-circuit current of 44.13 mA/cm² and an efficiency of 37.86% when considering an albedo coefficient of 0.5. Our study provides compelling evidence that incorporating metallic nanoparticles into the architecture of bifacial perovskite solar cells leads to a substantial enhancement in efficiency, especially within thinner absorber layers. Notably, this approach also mitigates the significant concerns related to precautionary measures associated with absorber materials containing lead.
