Abstract

A photovoltaic module is provided. A light absorbing array layer is arranged on a first surface, so that when the same incident light is irradiated on the first substrate, the incident light refractedto the first substrate by the light absorbing array lay is much larger than the light refracted to the first substrate when the light absorbing array layer is not provided. By providing the light-absorbing array layer on the first surface, the amount of incident light entering the first substrate can be increased, so that natural sunlight can be fully utilized. At the same time, the incident light can be refracted bilaterally by a plurality of spaced-apart convex structures, and a portion of the reflected light can also be refracted into the first substrate, so that more incident light entersthe solar cell panel. Therefore, by providing a plurality of convex structures arranged at intervals on the first surface of the first substrate, the incident light amount of the solar cell panel canbe increased, the light loss can be effectively reduced, and the output power of the photovoltaic module can be increased.

Description

technical field [0001] The present application relates to the technical field of photovoltaic power generation, in particular to a photovoltaic module. Background technique [0002] As a form of power generation in the field of new energy, photovoltaic power generation is widely used. How to improve the efficiency and power of photovoltaic modules and reduce production costs has become a major issue in the development of photovoltaic industry. Photovoltaic modules are composed of front glass, EVA, solar cells, EVA, a number of ribbons, plus a back plate or back glass, formed by lamination and packaging, so as to prevent the solar cells from being oxidized in contact with air and reducing power generation efficiency. [0003] However, after the light enters the module, part of the light leaks to the outside of the module due to the reflection of the cells and the back plate in the gap area of ​​the cells, and is not used. Moreover, encapsulation loss will occur after encapsu...
