Plug and Play Copper Pastes

 

ABOUT OUR TECHNOLOGY

Revolutionizing the Solar Industry

The team at Bert Thin Films believes that solar energy should be affordable for everyone.

Challenge

A solar cell includes a metal pattern to collect and conduct the electricity generated from the silicon. This metal is silver, which is expensive and in high demand. 

The silver is printed using simple screen printing processes and fired in high speed belt furnaces, processes that have been implemented for decades.

Others have attempted to replace the silver conductor with copper, which is far more abundant and less expensive, but their solutions have required introducing additional steps to the manufacturing processes and thus added expenses that offset the benefits of their copper paste. 

Bert Thin Film's Solution

The team at Bert Thin Films has invented and patented a unique copper paste, CuBert™, which is used as a direct substitute for the silver paste in the manufacturing process.

CuBert™ is printed and fired in the same manner as the silver paste; using the same screen-printing equipment and belt furnaces in use today by solar panel manufacturers.

CuBert™ is a direct plug-and-play replacement for the silver paste in the existing manufacturing process, so the cost benefits of the copper conductor can be fully and immediately realized by the manufacturers. And there is plenty to supply the expected industry growth.
