The heat-conducting organosilicon comprises a component A and a component B in a set weight ratio, wherein the component A comprises 5-20 parts by weight of hydrogen-containing silicone oil, 0.1-2 parts by weight of a catalyst and 0.1-2 parts by weight of an inhibitor; the component B comprises 40 to 60 parts by weight of vinyl polysiloxane, 1 to 20 parts by weight of a reinforcing filler and 5 to 50 partsby weight of a heat conduction filler. The heat-conducting organosilicon material provided by the invention is relatively good in heat-conducting property.

Description

technical field [0001] The invention relates to the technical field of photovoltaic components, in particular to a heat-conducting silicone, a photovoltaic component and a packaging method for the photovoltaic component. Background technique [0002] With the increasing awareness of energy conservation and environmental protection, solar power generation technology has developed rapidly. For a photovoltaic module, it usually includes a front plate, a battery sheet and a back sheet, and the battery sheet is connected between the front plate and the back sheet through an adhesive layer such as an adhesive film to complete the packaging of the battery sheet. During the use of this kind of photovoltaic module, the battery sheet will generate a certain amount of heat due to work, which will increase the temperature of the battery sheet, reduce the photoelectric conversion efficiency of the photovoltaic module, and reduce the power generation performance of the photovoltaic module...
