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:
- 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.
How atmospheric plasma works
Reactive gases are diffused toward the surface under the influence of electrical fields. Low molecular weight materials such as water, absorbed gases and hydrocarbon fragments are knocked off the surface to expose a clean, fresh bonding surface. At the same time a percentage of the reactive components with sufficient energy, bond to the freshly exposed surface changing the chemistry of the surface and imparting the desired functionalities.
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.
Free technical paper and lab trials
Enercon has written a new technical paper on the use of atmospheric plasma for thin film solar applications which details etching, cleaning and bonding trial data which confirms the technology’s effectiveness.
