Photovoltaic module

Abstract

The invention discloses a photovoltaic module. The photovoltaic module comprises glass and a back panel which are laminated, wherein a plurality of battery pieces are laid between the glass and the back panel, a gap exists between edges of adjacent battery pieces, a reflective layer is arranged in the gap, and a reflective surface of the reflective layer faces the glass. Sunlight irradiates the photovoltaic module, a light ray irradiating the gap is reflected to the glass under a reflective effect of the reflective layer at a gap position, is secondarily reflected by the glass and is returnedto the battery pieces, thus, the part of split light is collected by the battery piece, the light receiving efficiency of the photovoltaic module is improved, the output power of the photovoltaic assembly is improved, light cannot be absorbed or transmitted by the back panel, the back panel is prevented from absorbing sunlight to cause temperature rising, and the service lifetime of the photovoltaic module is prolonged.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a photovoltaic module. Background technique [0002] A photovoltaic module is a power generation module that uses sunlight to generate electricity. A photovoltaic module is obtained by connecting multiple single solar cells in series or in parallel and packaging them. Photovoltaic modules usually include glass, encapsulation material, cell sheet, encapsulation material and back sheet from top to bottom. After these materials are pressed together, they are encapsulated by a frame around them. [0003] Since multiple solar cells in each photovoltaic module are arranged in a matrix and tiled between the glass and the back plate, there are gaps between adjacent solar cells, and the positions corresponding to the upper and lower positions of the back plate are exposed, and the sunlight irradiates the photovoltaic When the module is installed, part of the light is irrad...

AI Technical Summary

Problems solved by technology

[0003] Since multiple solar cells in each photovoltaic module are arranged in a matrix and tiled between the glass and the back plate, there are gaps between adjacent solar cells, and the positions corresponding to the upper and lower positions of the back plate are exposed, and the sunlight irradiates the photovoltaic When the module is installed, part of the light is irradiated on the backplane through the gap between the cells, and this part of the light is absorbed or penetrated by the backplane, resulting in an increase in the temperature of the photovoltaic module and waste of light, which affects the service life of the photovoltaic module and efficiency

[0004] To sum up, how to solve the problem that the backplane absorbs light between the gaps of the cells, causing the temperature rise of the photovoltaic module and the waste of light has become an urgent problem to be solved by those skilled in the art.
