LGTEC AG, a Swiss startup, has developed an innovative technology that will revolutionize the metallization of solar cells. This novel method allows the production of very fine grid lines for contacting solar cells without the use of silver, leading to significantly lower costs.

Until now, grid lines with a width of about 15 to 30 micrometers have been used for solar cells, produced by screen printing and a firing process. The new technology of LGTEC AG now allows these grid lines to be reduced to an impressive width of up to 10 micrometers (depending on required line conductance) and manufactured in a single process step without the use of silver.

The elimination of silver in the production of the grid lines brings about significant cost savings. Silver is a very expensive precious metal, with its price having risen sharply in recent years. By using alternative materials, the LGTEC AG technology can significantly reduce the production costs of solar cells.

As a solution provider for solar cell manufacturer, LGTEC AG aims to contribute to the decarbonization of our world.

这是一段关于瑞士初创公司LGTEC AG开发的一种革新性技术,可以改变太阳能电池金属化的说明。这种新方法可以在不使用银的情况下生产出非常细小的网格线(电极线),从而大大降低成本。

目前,太阳能电池使用的网格线宽度约30微米,是通过丝网印刷和烧结工艺制造的。LGTEC AG的新技术可以将网格线宽度减小至10微米以内,并且只需单一工艺步骤即可完成,无需使用银。

避免在网格线生产中使用银,可以带来巨大的成本节省。银是一种昂贵的贵金属,近年价格上涨明显。LGTEC AG的技术采用替代材料,可以大幅降低太阳能电池的生产成本。
