Research On Current Situation and Future Outlook of Solar Cells

Abstract

Solar energy, as a clean and sustainable energy source, is regarded as one of the key technologies for renewable energy. Solar cells as the core of photovoltaic technology, can directly convert light energy into electricity through the photovoltaic effect without emitting greenhouse gases during operation, which played a significant role in energy security and environmental protection. This paper systematically reviews the research progress of solar cell technology through literature research, focusing on the working principles, technical characteristics, and application status of crystalline silicon cells, thin-film cells, and emerging perovskite cells. The study finds that crystalline silicon cells dominate the market due to their high conversion efficiency (22%-24%) and stability, but the production process of crystalline silicon can be energy-intensive, and its material is sensitive to temperature. In contrast, thin-film cells have advantages in material consumption and manufacturing energy consumption, but its efficiency improvement faces several bottlenecks and the market thin-film solar is facing remains relatively narrow. Perovskite cells exhibit extremely high efficiency potential (photoelectric conversion rate exceeding 29%), but the material stability problems and lead leakage risks have hindered the commercialization process of perovskite cells. Additionally, the paper explores the role of energy storage technologies, intelligent management systems, and material optimization in promoting the future development of solar technology.
