Abstract

The invention provides a manufacturing method of a low-melting-point metal device and a manufacturing method of a solar cell, and relates to the technical field of low-melting-point metal. The manufacturing method of the low-melting-point metal device comprises the steps of: providing a base material and a packaging film; forming a low-melting-point metal pattern on the base material by using low-melting-point metal; cooling the low-melting-point metal pattern to solidify the low-melting-point metal in the low-melting-point metal pattern; covering the surface, on which the low-melting-point metal pattern is formed, of the base material with the packaging film, and applying pressure to the packaging film and / or the base material to complete packaging of the low-melting-point metal pattern;and heating the low-melting-point metal pattern to room temperature, and melting the low-melting-point metal pattern to obtain the low-melting-point metal device. According to the technical scheme, the problem of deformation or damage of the low-melting-point metal pattern caused by overflow of the low-melting-point metal when the low-melting-point metal pattern is packaged by using the packagingfilm can be solved.

Description

technical field [0001] The invention relates to the technical field of low-melting-point metals, in particular to a method for manufacturing a low-melting-point metal device and a method for manufacturing a solar cell. Background technique [0002] The melting point of low-melting-point metals is lower than 300 degrees Celsius. It has the advantages of good electrical conductivity, low melting point, and good thermal conductivity. It has become an emerging functional material that has developed rapidly in recent years. In the process of applying low-melting-point metals, after the low-melting-point metal patterns are fabricated on the substrate, it is usually necessary to package the low-melting-point metal patterns to effectively protect the low-melting-point metal patterns and improve the stability of low-melting-point metal devices. [0003] At present, commonly used packaging methods include the following: [0004] The first one is to fill the uncured PDMS or silica gel...
