Problems solved by technology

[0004] However, existing photovoltaic modules are usually encapsulated in glass, such as figure 1 As shown, it is a cross-sectional schematic diagram of a photovoltaic module in the prior art, and its photovoltaic module includes encapsulation glass 10 on the light incident surface, adhesive layers EVA 11, 13, monocrystalline silicon or polycrystalline silicon solar cells 12, TPT backplane 14, components The frame 15 is sealed and installed. This type of photovoltaic module is heavy and fragile. When it is used on the top of a building or in the construction of a photovoltaic power station, it puts forward higher requirements for the supporting structure of the photovoltaic module, which increases the construction cost. cost

Abstract

The invention discloses a light photovoltaic module. The light photovoltaic module comprises a back plate, a first insulation layer, a solar cell piece, a second insulation layer and a light transmitting membrane, and further comprises a sealing installation frame located on the peripheral sides of the back plate, the first insulation layer, the solar cell piece, the second insulation layer and the light transmitting membrane. An adhesive layer is arranged between the back plate and the first insulation layer, an adhesive layer is arranged between the first insulation layer and the solar cell piece, an adhesive layer is arranged between the solar cell piece and the second insulation layer, and an adhesive layer is arranged between the second insulation layer and the light transmitting membrane. A shady face of the photovoltaic module is formed by the bottom face of the back plate, a light receiving face of the photovoltaic module is formed by the surface of the light transmitting membrane, and at least one surface of the light transmitting membrane is provided with a plurality of concave-convex structures which are evenly arranged. The photovoltaic module is high in sunlight condensation rate, the receiving area of the solar cell piece is large, and the photoelectric conversion efficiency is high; the photovoltaic module is low in weight and is not broken easily in the transportation and installation operation; meanwhile, the light transmitting membrane is high in light transmitting rate and has a good effect of blocking moisture.

Description

technical field [0001] The invention relates to the technical field of photovoltaic energy, in particular to a light-weight photovoltaic module. Background technique [0002] Solar cells, also known as "solar chips" or "photovoltaic cells", are photoelectric semiconductor sheets that use sunlight to generate electricity directly. Solar cells have a wide range of applications, and have entered the fields of industry, commerce, agriculture, communications, household appliances, and public facilities from the military field and aerospace fields, especially in remote areas, mountains, deserts, islands, and rural areas. To use in order to save expensive transmission lines. [0003] During the application process of solar cells, solar cell modules of different sizes need to be fabricated. Multiple solar cells are connected in series to form a solar cell module with higher voltage output, which is often called a photovoltaic module. The photovoltaic module made can be laid on the...
