The utility model relates to a novel efficient solar photovoltaic-light and heat collector, include: the photovoltaic cell comprises a photovoltaic cell glass film, a photovoltaic cell, an EVA (ethylene-vinyl acetate) adhesive film, an electric insulating layer, a blowing expansion plate and a heat insulating material. The utility model has the advantages that: this subassembly adopts neotype inflation board runner structural design, adopts the inflation board of runner design optimization promptly, compares and has higher heat collection efficiency with the PV/T subassembly of using air or water as heat collecting medium and the inflation board that does not optimize through the runner design, realizes more efficient thermal-arrest and photovoltaic cell's cooling, and the inflation board runner that forms by hexagonal runner and latticed runner combination in addition can realize more even temperature distribution to improve photovoltaic cell current output's stability and improve the life-span. The component has compact structure, high efficiency, light weight and attractive appearance, reduces the occupied area, improves the power generation and heat pump efficiency, and has important significance in the fields of popularization of renewable energy utilization and green buildings. |
