Lightweight and modular solar modules

Abstract

Disclosed is a light-weight modularized solar cell assembly, comprising a backboard, an insulating layer, a solar cell sheet, a concave-convex film and a light transmitting film which are provided successively, wherein an adhesive layer is provided between the backboard, the insulating layer, the solar cell sheet, the concave-convex film and the light transmission film; the bottom surface of the backboard forms a backlight surface of the solar cell assembly; the surface of the light transmitting film forms a light receiving surface of the solar cell assembly; the concave-convex film is located below the light-transmitting film; and several concave-convex structures which are arranged uniformly are formed on the surface, facing the light transmission film, of the concave-convex film. The light-weight modularized solar cell assembly in the present invention is low in weight, and is easy to install and transport, thereby reducing the costs of engineering construction. By providing a concave-convex film, the solar cell assembly in the present invention improves a sunlight convergence ratio, improves the photoelectric conversion efficiency, and relatively increases a light receiving area of a light receiving surface of the solar cell assembly. In addition, the solar cell assembly in the present invention is set in a modularized mode, facilitating promotion and application.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a lightweight modular solar cell assembly. Background technique [0002] Solar cells, also known as "solar chips" or "photovoltaic cells", are photoelectric semiconductor sheets that use sunlight to generate electricity directly. When it is illuminated by light, it can output voltage instantaneously and generate current when there is a loop. Solar cells have a wide range of applications, and they have entered industries, commerce, agriculture, communications, household appliances, and public facilities from military and aerospace fields, and can be used in remote areas, mountains, deserts, islands, and rural areas. Save expensive transmission lines. [0003] During the application process, the solar cell can be made into a solar cell module. For example, the manufactured solar cell module can be laid on the top of the building to supply power inside the building, and can a...

Problems solved by technology

[0004] However, the existing solar modules are usually of high quality. When they are applied on the top of buildings or in the construction of solar power stations, etc., higher requirements are placed on the supporting structure of solar modules, which increases the cost of engineering construction.

In addition, due to the limitation of the photoelectric conversion efficiency of solar cells and the light-receiving area, the existing solar cell modules have low luminous efficiency and cannot meet the needs of high-power electricity applications.
