Concentrating photovoltaic power generation light guiding and converging funnel

Abstract

The invention relates to a concentrating photovoltaic converging part, in particular to a concentrating photovoltaic power generation light guiding and converging funnel, and belongs to the technical field of solar power generation. The concentrating photovoltaic power generation light guiding and converging funnel comprises a light guiding funnel body, a fixed lens funnel, a connecting plate and fixed installation holes. A lower end opening of the light guiding funnel body is directly welded to the upper end of the fixed lens funnel, the bottom end of the fixed lens funnel is directly welded to the connecting plate, the two opposite faces of the connecting plate are provided with the two fixed installation holes. The concentrating photovoltaic power generation light guiding and converging funnel is simple in machining technology, simple in product structure, few in consumed material and light in weight; the concentrating photovoltaic power generation light guiding and converging funnel can not be deformed in the packaging and transportation processes and the follow-up installation process, and meanwhile it is guaranteed that converged sunlight is completely gathered to the effective face of a concentrating photovoltaic cell chip; by means of the concentrating photovoltaic power generation light guiding and converging funnel, second condensing lenses can be fixed.

Description

technical field [0001] The invention relates to a concentrating photovoltaic concentrating component, in particular to a concentrating photovoltaic 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 gu...

Problems solved by technology

[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 function, because its connecting plate (also called fixed mounting feet in some places) is in the shape of "L" or right angle " Z" shape, directly connected from the upper port of the light guide funnel, in the process of production, packaging and transportation or later installation, the right angle is not easy to get 90° guarantee, so that the light guide to the effective surface of the concentrating photovoltaic cell chip appears. deviation, leading to a reduction in photovoltaic conversion efficiency; at the same time, because the "L" or "Z" shaped products use more materials than the "one" shaped products, and the number of light guide funnels used in each concentrated photovoltaic module is extremely large, so The overall weight of concentrating photovoltaic modules will increase, and the process of processing "L" or "Z" shapes is also more complicated. At the same time, all light guide funnels do not have the function of fixedly installing lenses
