Photovoltaic component, photovoltaic and photo-thermal integrated component and manufacturing methods thereof

Abstract

The invention relates to a photovoltaic component, a photovoltaic and photo-thermal integrated component and manufacturing methods thereof. The photovoltaic component comprises front plate glass, a first back plate, an adhesive layer located between the front plate glass and the first back plate, and a battery piece located in the adhesive layer, wherein the photovoltaic component at least further comprises a hollow layer located between the front plate glass and the adhesive layer. According to the photovoltaic component and the photovoltaic and photo-thermal integrated component, the hollow layer is included, so that the photovoltaic and photo-thermal integrated component has a local thermal insulation function, front baffle glass and a thermal insulation hollow layer do not have to be added directly in front of the light receiving surface of the component, and the structure and the manufacturing process of the photovoltaic and photo-thermal integrated component are simplified.

Description

technical field [0001] The invention relates to the field of solar photovoltaic photothermal, in particular to a solar photovoltaic module with a hollow structure, a photovoltaic photothermal integrated module and a manufacturing method thereof. Background technique [0002] With the continuous development of industry, the consumption of energy is increasing day by day, prompting people to devote themselves to the development of new energy. As a green energy, solar energy is undoubtedly the most potential renewable energy on earth. According to different energy conversion methods, the use of solar energy can be divided into two types: photovoltaic and photothermal. "Photovoltaic" refers to the method of directly converting light energy into electrical energy by using the photovoltaic effect of the semiconductor interface, and "photothermal" refers to the method of using materials to absorb light energy of different wavelengths in the solar radiation spectrum and convert it ...

AI Technical Summary

Problems solved by technology

Therefore, in the photovoltaic photothermal integrated module constructed in the above-mentioned manner, although it can play a role of heat preservation to improve thermal efficiency, from figure 2 From the shown structure, it can be seen that since an air layer and a piece of front glass 15 are added on the front glass 11 of the photovoltaic module, light passes through the front glass 15 and the air layer. At 16, the transmittance is reduced, which leads to more light attenuation, thereby reducing the conversion efficiency of photovoltaics

[0007] In addition, due to the need to additionally set the front shield glass 15 and the air layer 16, the structure of the photovoltaic photothermal integrated module is complicated, and the manufacturing process is cumbersome and inefficient.
