Problems solved by technology

At present, the conventional method in the industry to increase the power of double-sided double-glass is: use partial white glazed high-reflective glass on the back to meet the high reflectivity and at the same time minimize the shading of the back of the battery, but this method accounts for about 40% of the shading area on the back of the battery. %, it still has a certain impact on the backside power generation of bifacial modules

Abstract

A double-sided double-glass photovoltaic module comprises a front panel glass laminated in sequence from top to bottom, first encapsulation film, battery layer, A second encapsulation adhesive film and a back plate glass, the battery sheet layer comprises a plurality of double-sided solar cell sheets arranged in tiles, the battery sheet layer further comprises a light-transmitting film disposed between adjacent the double-sided solar cell sheets, A space is provided between adjacent double-sided solar cell sheets, The light transmitting film has an edge portion fixedly connected to the adjacent double-sided solar cell sheets and a body corresponding to the spacing. A reflective metal layer is respectively formed on the front surface and the back surface of the body of the light transmitting film, so as to increase the utilization rate of incident light and increase the module power without shielding the battery sheets.

Description

technical field [0001] The invention belongs to the field of solar cells, and in particular relates to a double-sided double-glass photovoltaic module. Background technique [0002] Recently, with the continuous innovation of photovoltaic technology, the photovoltaic industry and research institutions have paid more attention to the power improvement of photovoltaic modules. With the maturity of double-sided battery technology and the long life and low cost of double-glass modules, the market demand for double-sided double-glass is increasing. Due to double-sided double-glass double-sided power generation, the required module design does not block the back of the battery, and the efficiency enhancement method used for conventional double-glass, such as the white EVA method on the back, is no longer applicable. At present, the conventional method in the industry to increase the power of double-sided double-glass is: use partial white glazed high-reflective glass on the back ...
