Concentrating solar power generation light-guiding convergence hopper

Abstract

The invention relates to a concentrating photovoltaic condensation component, in particular to a concentrating solar power generation light-guiding convergence hopper, and belongs to the technical field of solar power generation. The concentrating solar power generation light-guiding convergence hopper comprises a light guiding hopper body, a fixed lens hopper body, a connecting plate and fixing installing holes, wherein the lower port of the light guiding hopper body is directly welded to the upper end of the fixing lens hopper body, the upper port of the light guiding hopper body is rectangular, the bottom end of the fixed lens hopper body is directly welded to the connecting plate, the lower port of the fixed lens hopper body is rectangular, and the two fixing installing holes are formed in the two opposite surfaces of the connecting plate respectively. According to the concentrating solar power generation light-guiding convergence hopper, the light guiding hopper body is simple in machining process and product structure, low in material consumption and light in weight. The light guiding hopper body cannot deform in the packaging and transport process and the follow-up installing process, and meanwhile it is ensured that converged sunlight completely concentrates on the effective surface of a concentrating photovoltaic cell chip. According to the concentrating solar power generation light-guiding convergence hopper, a secondary condenser lens can be fixed; in addition, focal spots converged through a Fresnel lens will converge on the effective area of a concentrating solar cell in a complete superposition mode through the light guiding hopper body in a certain time period. A motor of a solar energy tracker can only work one time in a set time period, and therefore the power supply power for the motor is greatly reduced, and more energy is saved.

Description

technical field [0001] The invention relates to a concentrating photovoltaic concentrating component, in particular to a concentrating solar power generation light guiding and converging funnel, which belongs to the technical field of solar power generation. Background technique [0002] In the concentrated photovoltaic power generation system, the lens is mainly used to gather sunlight to the effective surface of the concentrated photovoltaic cell chip, so as to achieve the purpose of power generation. The current lens used generally has a convergence rate of about 80%. According to the current calculation, every 1% increase in conversion efficiency will reduce the electricity price by about 5%. Therefore, improving the lens convergence rate has become an important research topic for various companies. one. [0003] At present, some enterprises use the light guide funnel to improve the convergence rate of the lens. Although the light guide funnel has a good light guide fun...

Problems solved by technology

However, in practical applications, the sun is moving at any time, which will cause the focal spot that converges from the Fresnel lens after a period of time to pass through the light guide funnel and will not completely coincide with the effective area of ​​the concentrating solar cell. resulting in a decrease in conversion efficiency
