Abstract

The invention belongs to the technical field of photovoltaic cells and relates to a packaged photovoltaic cell component and a preparation method thereof. The component sequentially comprises a covering layer, a transparent conductive film layer, an adhesive upper layer, a photovoltaic cell, an adhesive lower layer and a substrate layer from top to bottom; and the adhesive upper layer is an improved ethylene-vinyl acetate copolymer thin film layer. The preparation method comprises the following steps: fully and uniformly mixing aluminum oxide and a coupling agent according to the part by weight, drying at a temperature of 80 DEG C, grinding and dispersing and adding in a mixture of a curing agent and EVA pellets; then adding anthriscus sylvestris ethyl ether and uniformly mixing; and pouring the mixture into an extruder for blending extrusion. Compared with the prior art, the packaged photovoltaic cell component provided by the invention has the benefits that through mixing the anthriscus sylvestris ethyl ether into a vinyl-vinyl acetate copolymer, the adhesive upper layer is not easy to degrade when meeting with light with a wavelength of more than 280 nm, so that the degradationwavelength range of the vinyl-vinyl acetate copolymer is shortened; and moreover, the anthriscus sylvestris ethyl ether can also improve the initial adhesive strength of an adhesive.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic cells, and relates to a packaged photovoltaic cell component with high photoelectric conversion efficiency and a preparation method thereof. Background technique [0002] With the continuous development of social economy and the continuous progress of human civilization, human demand for energy continues to grow, and energy issues have become global issues. The chemical energy and nuclear energy used by human beings are not clean energy. At the same time, the existing exploitable energy can no longer maintain the sustainable development of human beings. Making full use of solar energy has become an inevitable trend. Solar energy is clean and environmentally friendly, inexhaustible, and does not produce any environmental pollution. It is the most abundant renewable energy available to human beings. [0003] Currently, there are two main types of photovoltaic cells for solar applications: wafe...
