Abstract

The invention provides a high thermal conductivity photovoltaic cell component and a manufacturing method thereof. The manufacturing method comprises steps that a plurality of protrusions are formedon an upper surface of a metal substrate, and a plurality of blind holes along the thickness direction of the metal substrate are formed in the lower surface of the metal substrate; EVA hot melt adhesive particles are disposed in gaps between the adjacent protrusions in a filled manner, and thermocompression bonding processing is carried out, and the a first EVA adhesive layer is formed on a metalsheet; a second EVA adhesive layer is disposed on the surface of the metal sheet in a sprayed way, and then a solar cell layer, a third EVA adhesive layer, and a glass cover plate are sequentially disposed on the second EVA adhesive layer, and each protrusion is used to support one solar cell, and then the protrusions are respectively corresponding to the solar cells; lamination processing is carried out, and then the high thermal conductivity photovoltaic cell component is formed.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cells, in particular to a high thermal conductivity photovoltaic cell component and a manufacturing method thereof. Background technique [0002] Existing photovoltaic cell modules generally include tempered glass, adhesive layer, cell sheet layer, adhesive layer and back sheet. Among them, the role of tempered glass is to protect the main body of power generation (cell), and the light transmittance is generally above 91%. The life of the module, the adhesive layer exposed to the air is prone to aging and yellowing, which affects the light transmittance of the module, thereby affecting the power generation quality of the module. In addition to the quality of the adhesive layer itself, the lamination process of the module manufacturer is also very influential; The main function of the main body of power generation is to generate electricity. The mainstream of the power generation main body ma...
