High-efficiency low-condensation photovoltaic assembly

Abstract

The invention relates to a high-efficiency low-condensation photovoltaic assembly, which comprises a glass cover plate, a condensation reflector, a solar panel and a metal matrix. Each condensation reflector unit comprises two adjacent reflection surfaces in two reflection modules; each reflection module comprises two integral reflection surfaces which are back to back with each other; the upper surfaces of the reflection surfaces are compound paraboloids and the lower surfaces thereof are planes; a heat dissipation air channel is naturally formed between the two reflection surfaces; mirror reflection films are fixed on the reflection modules with adhesives; the solar panel is packaged at the opening of the lower end of the reflector; sun light is reflected to the solar panel through the reflector for photoelectric conversion; the metal matrix is a plane; the reflection modules are fixed on the metal matrix with screws; the solar panel and the condensation reflector are closed in a frame by a transparent cover plate; and gaps are reserved between the transparent cover plate and the reflection modules. The invention has reasonable structural design, even illumination, high efficiency, natural heat dissipation, simple and convenient manufacture and installation, flexible assembly and lower cost and does not need a tracking system and can be widely popularized and applied.

Description

Technical field: [0001] The invention relates to a high-efficiency non-tracking low-concentration solar cell module. Background technique: [0002] With the gradual depletion of fossil energy, the utilization of renewable energy has become a global research and development hotspot. Among new energy sources, photovoltaic power generation has attracted much attention. In the past two decades, the production technology and process have been continuously updated, and the cost of photovoltaic power generation has continued to decline, but the cost of power generation is still far higher than other conventional power generation technologies, which is 3-5 times the cost of conventional power generation, and is also higher than that of wind power. Power generation technology, so photovoltaic power generation technology has not yet fully entered the market. Judging from the recent market supply and demand characteristics, the demand for solar cells has increased sharply, the supply...

AI Technical Summary

Problems solved by technology

First of all, the intensity of solar radiation incident on the solar cell is not uniform, resulting in a decrease in photoelectric conversion efficiency; secondly, the solar radiation reflected by the lower end of the parabolic surface onto the solar cell has a large incident angle and is difficult to be absorbed by the solar cell; third, light concentration The temperature of the solar cell in the cavity is higher than that of the non-concentrating cell, which affects the power output of the module to a certain extent; fourth, the processing and manufacturing of the concentrator is difficult, and it is not suitable for mass production
