Abstract
A method for fabricating a photovoltaic (PV) module, including: (1) covering a polymer material on the side of the crystalline silicon solar cell attached with a solder ribbon followed by heating to allow bonding of the solder ribbon to the crystalline silicon solar cell, so as to obtain a solar cell module; (2) assembling several solar cell modules into a solar cell string, and connecting multiple solar cell strings to form a solar cell array; (3) laying sealing plates respectively on the front and back sides of the solar cell array to form a stacked body; and (4) subjecting the stacked body to lamination achieve an ohmic contact between the solder ribbon and the grid line, and transformation of the polymer material into a filler layer. This application further provides a PV module fabricated by such method, a solar cell module and a solar cell string.
