Abstract
The invention discloses a conductive back plate and a manufacturing method thereof, and a back contact photovoltaic module, relates to the technical field of photovoltaics, and aims to reduce the manufacturing difficulty of the conductive back plate, simplify the manufacturing process and improve the production efficiency. The manufacturing method of the conductive back plate comprises the following steps: providing a substrate; forming a pattern isolator on the substrate using a hydrophilic material; forming a conductive seed layer covering the pattern isolator on the whole surface of the substrate; removing the pattern isolator and the part, located on the pattern isolator, of the conductive seed layer by adopting a water washing method to form a patterned conductive layer; and growing a conductive circuit pattern by taking the patterned conductive layer as a seed layer. The conductive back plate and the manufacturing method thereof, and the back contact photovoltaic module are used for manufacturing the back contact photovoltaic module.
Description
technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a conductive backplane, a manufacturing method thereof, and a back-contact photovoltaic module. Background technique [0002] The positive and negative electrodes of the back-contact solar cell are both arranged on the back of the battery sheet, so that the blocking of sunlight by the front of the back-contact solar cell is greatly reduced, thereby improving the conversion efficiency of the solar cell. [0003] In order to reduce the interconnection resistance of back-contact photovoltaic modules and improve the efficiency of photovoltaic modules, a conductive backplane can be used to realize the conductive interconnection between back-contact solar cells. However, in the prior art, the manufacturing process of the conductive backplane is relatively complicated and the production efficiency is low. Contents of the invention [0004] The object of the present invention is...
