Problems solved by technology

[0003] However, in the production process, due to the influence of the material properties of the substrate (such as glass), it is easy to cause the substrate to be cracked and damaged, resulting in a decrease in yield and an increase in manufacturing costs.
In addition, there is a demand for non-standard size thin-film batteries on the application side. At this time, it is necessary to cut the intact or defective finished thin-film battery cells into the required size, and cutting the finished battery is easy to cause damage, even rupture and damage. waste, which increases manufacturing costs

Abstract

The invention provides a manufacturing method of a film cell. When a first substrate is damaged, damage-less areas are cut off and are disposed in a slot of a carrier member, the multiple damage-lessareas of the first substrates are spliced through the carrier member to form a spliced substrate corresponding to the first substrate, when the process enters the subsequent process, subsequent manufacturing is carried out through employing the process program and parameters same as the first substrate, not only can influence on the subsequent process be avoided, but also material waste is avoided, the material utilization rate is improved, the production yield of film cells is improved, and manufacturing cost is reduced. The invention further provides a manufacturing method of a non-standardfilm cell.

Description

technical field [0001] The invention relates to the technical field of thin film batteries, in particular to a method for manufacturing thin film batteries. Background technique [0002] With the increasing shortage of energy and the increasing emphasis on environmental protection, the proportion of countries investing in photovoltaic energy is increasing year by year. Among them, in the field of photovoltaic power generation, thin-film batteries are becoming a research hotspot in the industry due to their advantages of large area, high efficiency, low production cost, and high quality and reliability. The traditional thin-film battery production process is to connect multiple thin-film solar cell units in series with each other through an interconnection structure, and assemble them on a large substrate. In the process of large-scale continuous industrial production, standardized battery components with uniform specifications are formed. [0003] However, due to the influ...
