Abstract

The invention discloses a photovoltaic cover plate. The photovoltaic cover plate is a cover plate for packaging a laminated solar cell module of a photovoltaic module; a battery piece accommodating groove is formed in the first surface of the photovoltaic cover plate, and the battery piece accommodating groove is a groove for accommodating a convex part of the laminated solar cell module; the first surface is the surface, close to the laminated solar cell module, of the photovoltaic cover plate. According to the invention, the surface of the photovoltaic cover plate is provided with the cell accommodating groove matched with the laminated solar cell module; therefore, the photovoltaic cover plate is in full contact with the laminated solar cell module. The stress in the welding or laminating process is uniformly distributed on the surface of the whole laminated solar cell, so that the possibility of hidden cracks or fragments of the laminated solar cell is greatly reduced, and meanwhile, the invention also provides a photovoltaic module with the beneficial effects.

Description

technical field [0001] The invention relates to the field of photovoltaic new energy, in particular to a photovoltaic cover plate and a photovoltaic module. Background technique [0002] As an inexhaustible clean energy, solar energy has been paid more and more attention by people from all walks of life. The role of solar cells is to convert solar energy into electrical energy and drive the terminal load to work. In recent years, photovoltaic module technology has achieved rapid development, and the continuous innovation of module technology is of great significance to the realization of grid parity for photovoltaic power generation. [0003] As the demand for photovoltaic cost reduction and efficiency increase becomes more and more intense, the market's demand for high power components is becoming more and more stringent. Therefore, high packaging density components have gradually entered the public eye, such as shingled and patchwork components. Modules use the overlappi...
