Abstract

The invention provides a photovoltaic-photocatalytic combination system based on the lens condensation principle, and belongs to the field of the solar comprehensive utilization engineering. The system is characterized in that the solar photovoltaic power generation and the solar photocatalytic performance are combined to achieve the photovoltaic conversion and sewage purifying functions; a photocatalytic system comprises a flat transparent glass cover plate, a photocatalytic agent, sewage and a parabolic transparent glass cover plate; the photocatalytic system is of a convex lens structure using water as a filling medium and used for collecting solar to a photovoltaic battery; an aluminum plate of the photovoltaic system has the effects of improving radiating and collecting light, and therefore, the power generation efficiency of the photovoltaic battery can be increased. With the adoption of the system, the solar spectrum utilization range is expanded, and therefore, the total solar utilization efficiency can be increased.

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...
