Abstract

The invention relates to a photovoltaic tile comprising a surface layer, an upper ethylene-vinyl acetate copolymer layer, a solar cell layer, an lower ethylene-vinyl acetate copolymer layer and a backboard layer which are stacked and packaged successively from top to bottom, wherein the surface layer is tempered glass, the backboard layer comprises an organic packaging layer, a silicon dioxide layer, a light reflective layer, a glass plate, a heat dissipation layer and a black polyvinyl fluoride composite film which are stacked successively from top to bottom, the solar cell layer comprises a plurality of solar cells arranged in a matrix. The solar cell module has a very good shading effect, can be used as a roof photovoltaic tile, has good hail resistance, and can be used in a variety of complex weather conditions.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a photovoltaic tile. Background technique [0002] Due to the increasingly serious global energy crisis and environmental problems, people's demand for new energy and non-polluting renewable energy is becoming more and more urgent. Solar photovoltaic power generation is a promising technical field in new energy and renewable energy. [0003] The most basic components of solar photovoltaic power generation are solar cells, including monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film batteries. A solar panel composed of one or more solar cells is called a photovoltaic module, or a solar cell module. A solar cell module is a device that converts solar energy into electrical energy. It has various installation forms, is safe and pollution-free, and is inexhaustible. Inexhaustible advantages, so it has been vigorously developed. [0004] At present...
