Durable photovoltaic component

Abstract

The invention discloses a durable photovoltaic component, which comprises an upper cover plate, an EVA (Ethylene Vinyl-Acetate) adhesive film, a monocrystalline silicone battery component string, a backboard, a frame and a junction box, wherein the upper cover plate, the EVA adhesive film, the monocrystalline silicon battery component string and the backboard are laminated into a component by a laminating machine after being sequentially stacked from top to bottom, then the junction box is adhered to the back surface of the component, and the frame is finally mounted on the component; the upper cover plate is tempered glass of which the surface is coated with a nanometer titanium dioxide coating. Through the adoption of the scheme, the photovoltaic component is high in photoelectric conversion efficiency, and meanwhile, the service life can reach more than 25 years.

Description

technical field [0001] The invention relates to the field of solar photovoltaic power generation equipment, in particular to a durable photovoltaic module. Background technique [0002] Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. [0003] The structure of a solar photovoltaic module mainly includes a top cover, an adhesive, a cell, a backplane, a frame and a junction box. The packaged photovoltaic modules need to be placed in the open air. After a period of use, the dust particles in the air will be adsorbed on the cover plate of the photovoltaic module, forming a light-blocking dust covering layer, thereby reducing the photoelectric conversion rate of the photovoltaic module, and at the same time, the large pieces are opaque The coverage of pollutants will also produce a hot spot effect, which will lead to local high temperature of photovoltaic modul...

AI Technical Summary

Problems solved by technology

The packaged photovoltaic modules need to be placed in the open air. After a period of use, the dust particles in the air will be adsorbed on the cover plate of the photovoltaic module, forming a light-blocking dust covering layer, thereby reducing the photoelectric conversion rate of the photovoltaic module, and at the same time, the large pieces are opaque The coverage of pollutants will also produce hot spot effect, which will lead to local high temperature of photovoltaic modules until they are burned and scrapped

It can be seen that the natural resistance of solar photovoltaic modules is poor, and long-term exposure to the air will cause problems such as attenuation of efficiency and difficulty in cleaning after the surface accumulates ash. Therefore, the photoelectric conversion efficiency of existing photovoltaic modules is low, and the service life generally cannot exceed 20 years
