Changzhou Weida launched the crystalline silicon double glass BIPV module process

solar photovoltaic laminated glass is to clamp solar cells between two layers of glass, and closely bond them with the inner and outer layers of glass through adhesive film. There are two kinds of amorphous silicon laminated glass and crystal 88 solvent based rubber asphalt waterproof coating silicon laminated glass, with a melting point of more than 1000 ° C. At present, crystalline silicon photovoltaic modules made of traditional packaging materials are not ideal for expanding the scope of application in photovoltaic building integration (BIPV) paper products due to their bonding strength, safety, light transmittance and other reasons. Many famous companies in China have been trying to use traditional technology and equipment to process components that meet the building curtain wall, but they have not found a very satisfactory solution

Changzhou Weida company recently introduced new technology and current equipment to make "double glass crystalline silicon photovoltaic modules". At the same time, ensure that the crystalline silicon photovoltaic modules produced by this process pass the 3C certification at home. The crystalline silicon double glass photovoltaic module is composed of two pieces of tempered glass, PVB film is used in the middle to compound photovoltaic cells to form a composite layer, and the cells are composed of wires in series and in parallel to collect leads, which are really an integral component. Its component structure is: 3.2mm ultra white tempered glass +0. 76pvb + crystalline silicon battery +0. 76pvb (color) + tempered glass (3. Mm)

according to the introduction of the head of Weida company, the cost of the new process is close to that of the traditional component process, but the polysilicon battery module encapsulated by the new PVB process has high safety when used in BIPV, which fully conforms to the compulsory certification (3C certification) of domestic building curtain wall, and is cheaper and has a high conversion rate compared with amorphous silicon thin film battery module. At the same time, PVB on the second floor can be used in a variety of architectural requirements by adjusting a variety of colors to suit the aesthetics of components
