摘要

This study introduces an innovative technical framework to tackle the elevated expenses of conventional silicon-based cells, the instability of thin-film cells, and the suboptimal efficiency of current photovoltaic systems. The proposed method seeks to lower prices, enhance conversion efficiency, and guarantee long-term stability through the utilization of perovskite materials, optimization of production processes, and improvement of system integration. Experimental findings reveal that at a high irradiation of 1400 W/m2, perovskite solar cells attain a photoelectric conversion efficiency of 26%, sustaining 22% efficiency at a temperature of 45°C, hence exhibiting robust performance across diverse environments. The total unit production cost of perovskite materials is assessed at US$205, markedly cheaper than that of silicon-based and thin-film alternatives. Optimized perovskite composites facilitated improved light absorption and carrier transport, achieving electron mobility of 42.3 cm2/V·s and total mobility of 29.1 cm2/V·s. System-level enhancements comprised optimized electrical connections, diminished contact resistance, and improved heat dissipation design, resulting in a surface temperature differential of 4.0 °C. Moreover, innovative packaging materials, including polytetrafluoroethylene, enhanced thermal stability to 2500 h and improved environmental resistance, hence extending the longevity of solar cells. These integrated developments offer a viable and cost-effective tactic for the widespread implementation of high-efficiency solar photovoltaic systems.
