German and Belgian scientists have jointly developed a perovskite/CIS stacked solar cell with a photoelectric conversion efficiency of 24.9% (nearly 25%), setting a record for similar technologies. This battery is lightweight and flexible, and can be applied in scenarios such as construction, automobiles, and portable devices. Stacking technology can absorb sunlight of different wavelengths, and this type of battery is expected to increase efficiency to over 30% in the future.

The article explores the impact of snow accumulation in cold seasons on solar panels and the corresponding countermeasures. Snow accumulation will significantly reduce power generation, and users without grid connection will be more affected, but snow reflection can slightly improve performance. The coping strategies include regular snow removal, increasing the angle of panel installation, and reserving space below the panel to ensure power generation efficiency.

The article introduces the service life and influencing factors of solar panels. The dropper board in crystalline silicon solar panels is used for about 5 years, and the laminated board that meets TUV standards can last up to 25 years; The lifespan of amorphous silicon solar panels is 10-15 years. Lighting, temperature, component quality, and maintenance can affect its performance, with an overall expected lifespan of over 20 years. Reasonable selection and maintenance can ensure profitability.

The article introduces four energy storage technologies in photovoltaic power generation. Due to the large fluctuations in photovoltaic output caused by environmental factors, energy storage systems are crucial for their stable grid connection. The four technologies are battery energy storage, supercapacitor energy storage, flywheel energy storage, and superconducting energy storage, each with its own advantages and disadvantages, which can ensure system stability, solve power quality problems, and promote the development of renewable energy.

The article answers the question of whether photovoltaic power plants emit radiation. Photovoltaic power plants convert sunlight into direct current through semiconductors, and then convert it into alternating current through inverters. The process does not involve chemical changes or nuclear reactions, and does not produce harmful short wave radiation. Although inverters have switching frequencies, they have metal shielding and comply with electromagnetic compatibility certification, so there is no need to worry about their radiation safety.
