Description

A photovoltaic module

Technical Field

The present invention relates to the field of photovoltaic technology, and more particularly to a photovoltaic module.

Background Art

Photovoltaic refers to solar photovoltaic conversion technology, also known as solar photovoltaic technology. It uses the photoelectric effect to convert solar energy into electrical energy. Photovoltaic technology is mainly composed of photovoltaic cells, which are semiconductor devices that can directly convert light energy into electrical energy. When light shines on a photovoltaic cell, the photons excite the electrons in the semiconductor to generate an electric current. These photovoltaic cells can be connected in series or in parallel to form a photovoltaic array to provide higher voltage and power output. Photovoltaic technology is widely used in solar power generation systems for applications such as power generation, power supply or energy storage. Photovoltaic reflective film is a thin film material applied to photovoltaic modules to improve the light absorption efficiency of photovoltaic modules. Photovoltaic modules are devices composed of multiple photovoltaic cells connected in series or in parallel. Photovoltaic modules are also called solar panels or solar cell groups. They usually consist of photovoltaic cells, backplanes, frames and connectors. Among them, it was found through searching that the patent application number CN201611201822.1 discloses a photovoltaic reflective film of a photovoltaic module, including a substrate, a microstructure reflective layer, and a fixed adhesive layer. The microstructure reflective layer is arranged on the upper surface of the substrate. The microstructure reflective layer includes a microstructure layer and a reflective layer. The reflective layer is coated on the surface of the microstructure layer, and the fixed adhesive layer is arranged on the lower surface of the substrate. The microstructure layer is composed of a plurality of micro triangular prisms arranged laterally in succession, and one side of the micro triangular prism is arranged on the upper surface of the substrate, and the ridge direction of the micro triangular prism is parallel to the length direction of the substrate. When the structure is in use, the microstructure layer is arranged in a flat state of the triangular prism, so that the incident light can be reflected in multiple directions and then absorbed by the battery cell, which can effectively increase the area of the reflection surface. However, when the area of the optical fiber is small during irradiation, it is not easy to gather and refract the light, which results in low utilization of the light source and thus low power generation efficiency.
