High-transmittance solar module structure

Abstract

The invention discloses a high-transmittance solar module structure, which comprises a cuboid frame, wherein a junction box is arranged at the bottom part of the frame, a back plate is arranged on thejunction box, an EVA encapsulation layer is arranged on the back plate, a silicon wafer battery is fixed on the EVA encapsulation adhesive layer, the surface of the silicon wafer battery has a plurality of channels, a strip-shaped triangular prism is arranged in each channel, the bottom part of each triangular prism is connected with the silicon wafer battery, and the top part of each triangularprism is abutted against the frame. According to the high-transmittance solar module structure, an EVA adhesive layer and a glass layer on the upper layer of the silicon wafer battery are removed andreplaced with the combination of the triangular prisms and the silicon wafer battery, the light absorption surface area of the silicon wafer battery is increased, the effect of relatively fixing the silicon wafer battery can be achieved, and the light absorption of contact portions between the triangular prisms and the silicon wafer battery is not affected due to the light reflection and light refraction effects of the triangular prisms.

Description

technical field [0001] The invention belongs to the field of solar energy application equipment, and in particular relates to a high-transparency solar module structure. Background technique [0002] A single solar cell cannot be directly used as a power source. As a power supply, several single cells must be connected in series and parallel and tightly packed into components. Solar cell modules (also called solar panels, photovoltaic modules) are the core part of the solar power generation system and the most important part of the solar power generation system. Its function is to convert the solar energy into electrical energy, or store it into the battery, or promote work load. The quality and cost of solar cell components will directly determine the quality and cost of the entire system. Solar cell modules are generally composed of high-efficiency crystalline silicon solar cells, ultra-white tempered glass, EVA, transparent TPT backplane and aluminum alloy frame. The ...
