Description

Technical field: [0001] The name of the invention is a photovoltaic-photocatalytic composite system based on the principle of lens concentration, which belongs to the field of comprehensive utilization of solar energy engineering. Background technique: [0002] As a clean and renewable energy source, solar energy has attracted more and more attention from domestic and foreign scholars. Among them, solar photovoltaic power generation technology has become an important way to utilize solar energy resources due to its advantages of safety, reliability, pollution-free and easy construction. However, solar cells are spectrally selective during operation, only part of the solar radiation (mainly concentrated in the visible light region) is converted into electrical energy, and most of the rest will be converted into heat energy, which will increase the temperature of the photovoltaic cell. Since the efficiency of photovoltaic cells decreases with the increase of temperature, espe...

Problems solved by technology

However, solar radiation will produce certain losses when passing through the catalytic system, which reduces the intensity of solar radiation reaching the surface of the photovoltaic cell and reduces the efficiency of the photovoltaic cell. Therefore, this structure is more conducive to the photocatalytic system and not conducive to the work of the photovoltaic system. run
