Abstract
With the increasing global energy demand and growing emphasis on environmental protection, photovoltaic (PV) power generation, as a clean and renewable energy form, has received extensive attention. To improve the efficiency of PV power systems, this study aims to explore multiple strategies addressing current issues such as low conversion efficiency and significant energy loss in PV systems. By integrating theoretical analysis with experimental research, this paper delves into material optimization, structural design, and intelligent control. In terms of materials, novel high-efficiency light-absorbing materials are employed to replace traditional silicon-based materials, significantly enhancing the photoelectric conversion efficiency. Structurally, an innovative multi-junction tandem cell structure is adopted to broaden the spectral response range and increase power generation. The intelligent control system dynamically adjusts operational parameters based on environmental factors such as light intensity and temperature, thereby reducing power loss. The results indicate that the application of new materials has increased photoelectric conversion efficiency by approximately 20%, while the multi-junction tandem structure has raised power generation per unit area by around 30%. Moreover, the intelligent control strategy effectively reduced energy loss by more than 15%. This research not only provides new insights into improving the efficiency of PV power systems and enriches the theoretical fr amework of PV technology but also contributes to advancing the PV industry towards higher efficiency and intelligence, promoting the widespread application of clean energy.
