Surface Treating For Solar Cell Converting

The art of optimizing continuous processing techniques for flexible materials has long been practiced in the converting industry. The accrued benefits range from consistent product quality and waste minimization to lower conversion cost per square meter. And a key component in the optimization of many web converting processes is consistent and uniform surface modification by corona discharge, flame or atmospheric plasma treatment systems to raise surface energy and/or clean web surfaces.

The future of economical thin film solar cell manufacturing is becoming dependent on new in-line process technology for high-speed continuous production. Enercon is pleased to offer a revolutionary atmospheric plasma surface treating technology for pretreatment of films and metals used in photovoltaic applications.

Enercon has pioneered the use of atmospheric plasma in the converting industry and has now adapted this technology for the solar industry. Atmospheric plasma offers a cost effective pretreatment solution as a precursor to coating, laminating and vacuum plasma deposition processes.

Improve surface adhesion

Atmospheric plasma technology is proven to clean and activate a wide variety of surface materials used in the construction of solar cells, including but not limited to:

• Aluminum
• Copper
• Stainless Steel
• EVA Film
• ITO Film
• PEN Film
• PET FIlm
• Polyimide Film Glass

A complex range of materials are employed to maximize solar efficiencies. Variable chemistry atmospheric plasma offers the ability to integrate continuous in-line manufacturing of rigid panels and flexible solar cells with a significant reduction in manufacturing costs. Atmospheric pressure gas phase plasma technology will become an essential technology for the economic fabrication of solar cells.

Flexible and rigid materials

One of the benefits of variable chemistry atmospheric plasma is that it may be configured in unique discharge devices to meet the needs of both flexible and rigid materials.
