ABSTRACT The tilt angle of a solar PV panel is critical factor in improving the efficiency photovoltaic (PV) systems. While tracking systems can enhance performance, they are typically not cost‐effective for residential areas. Alternatively, setting an optimized fixed or adjusting seasonally mitigate power losses. This study evaluates optimal seasonal angles and corresponding radiation on panels 10 major cities across Pakistan. A novel mathematical framework proposed to calculate using parameters such as alignment, azimuth, gradient, temporal angles. Seasonal adjustments shown increase intensity from during winter, significantly enhancing output power. For instance, improvement up density was observed at Quaid‐e‐Azam Solar Park crystalline cells. These findings demonstrate potential substantial improvements production through angles, particularly shorter winter days.

Abstract In the pursuit of higher conversion efficiency, PV industry has turned its focus towards perovskite-silicon tandem solar cells, which currently represent peak innovation. To surpass efficiency limits traditional single-junction researchers are exploring potential these cells by integrating merits perovskite and silicon. However, brings different challenges, such as deposition methods material misalignments. Thus, in this work, we using advanced simulation techniques, including Silvaco ATLAS’s Victory Process Device Simulator to imitate actual manufacturing processes. Primarily research work focuses on three scenarios: shunting, planarization conformal emulate experimental conditions. The obtained results show effectiveness process simulations accurately predicting improving performance cell. Two designed showed a 27.51% 29.08% respectively. This highlights importance tools for further development cell technology. Detailed device reported may pave way fabrication optimised perovskite/silicon

Although n-type tunneling oxide passivating contact (TOPCon) solar cells dominate the mainstream crystalline silicon (c-Si) technologies in photovoltaic market, p-type TOPCon also hold great potential to advance technology and may achieve efficiencies comparable heterojunction future due their unique passivation method. In this study, we investigate a method for introducing nitrogen (N) atoms into SiOx layer using N2O/NH3 mixture gas, aiming reduce B diffusion activation at SiOx/poly-Si interface within c-Si substrate. Our findings indicate that while incorporating N layers prepared with gas significantly suppresses substrate reduces both substrate, performance of N-doped remains relatively low. contrast, pure N2O demonstrates higher passivation, achieving an implied open-circuit voltage (iVoc) 723 mV low single-sided recombination current density (J0,s) 9.6 fA/cm2. This disparity is attributed presence SiOx, which leads thinner layer, reduced Si4+ content, increased surface defects, thereby counteracting beneficial effects doping. study provides comprehensive insights impact on TOPCon, along underlying mechanisms, providing valuable enhancing passivation.
