photovoltaic TPA

Efficient moisture prevention for sensitive thin-film substrates


Looking to protect substrate glasses against moisture?
Here are three reasons why photovoltaic TPA is your best choice

1.

High-precision butyl application on the edge of substrate glasses

2.

Active moisture barrier prior to the laminating process

3.

Possibility to integrate 24/7 operation in existing units

Encapsulate and actively protect against moisture


The photovoltaic TPA applies high-viscous butyl onto semiconductor thin-film substrates, effectively protecting the semiconductor against moisture. Prior to the laminating process, the machine accurately applies the material within a tenth of a millimeter from the edge of substrate glasses. Two high-performance pumps ensure that the viscous sealing material is always available – for real 24-hour operation.

The technology is based on decade-long experience in the construction of machines to produce insulating glass in which thermoplastic material is applied as a spacer between the glass plates. In the solar power industry, horizontal machines as well as vertical designs are used for sealing all types of semiconductors.

Option: Butyl sealing for junction boxes

Highest available butyl sealing precision
Active and effective vapour barrier prior to lamination process

Different application processes

  • Interruption-free application in the corners
  • Completely tight application
  • Interruption between the application in the corners
  • Corners are closed during the lamination process
