Component for improving power generation efficiency of n-type monocrystalline silicon photovoltaic cells and manufacturing method thereof

Abstract

The embodiment of the present invention discloses a component for improving the power generation efficiency of N-type monocrystalline silicon photovoltaic cells, including: a back plate; a lower adhesive film on the back plate, and the lower adhesive film includes a first adhesive film layer, a second The adhesive film layer and the reflective film layer between the first adhesive film layer and the second adhesive film layer, wherein the reflective film layer is formed by mixing polyhedral glass in the film material; Photovoltaic cells arranged at intervals; adhesive film on photovoltaic cells; glass plate on adhesive film. Polyhedral glass is mixed in the adhesive film material to form a reflective film layer in the lower adhesive film. Since the polyhedral glass in the reflective film layer has multiple reflective surfaces, the refractive index of sunlight can be effectively improved, and the reflective film layer will After multiple reflections and refractions, sunlight enters the back of the photovoltaic cell, thereby increasing the light receiving rate on the reverse side of the photovoltaic cell, thereby improving the power generation efficiency of the photovoltaic cell.
