Plasma in solar technology

KIOTO Photovoltaics GmbH from St. Veit in Austria has been using plasma in solar technology for years. Here, the plasma high-performance system plasmabrush® PB3 is integrated into the automated system for surface pre-treatment before bonding. Philipp Pollheimer from maintenance reports on his experiences with atmospheric pressure plasma in solar technology.

We currently use the plasmabrush® PB3 technology in both photovoltaic plants. We use it to pre-treat the adhesive surface of our solar junction boxes. In the second step, a 2-component adhesive is applied and the junction box is attached to the back of our photovoltaic modules.Philipp Pollheimer - KIOTO Photovoltaics GmbH

Chemical agents replaced by plasma

Pre-treatment with the plasmabrush® PB3 cleans and activates the bonding surface, thus ensuring optimum bonding adhesion. Previously, a similar adhesion result was achieved with chemical agents. However, we wanted to improve the safety of our employees and also reduce the burden on the environment to a certain extent.

Therefore, after some failures with other manufacturers, we decided to use this system from relyon plasma. We have discovered that this system is very easy to integrate into an automated system. This system has now been running for years in St.Veit without any problems. For this reason, the same system from relyon plasma was selected for the new system to be purchased in Wies in 2020.Philipp Pollheimer - KIOTO Photovoltaics GmbH
