K 2010: Photovoltaics from the Roll

October 27, 2010

A new type of solar barrier film developed by Evonik is making the production of flexible solar modules more profitable. Using the barrier film as the front cover makes it possible to produce thin-film solar modules cost-effectively in a roll-to-roll manufacturing process. The plastic film has similar barrier properties to the glass plates used in the past: Not only is it weather and UV-resistant, it is also highly transparent. This combination permits low-cost, efficient thin-film technology with a long life.

Up to now, suitable films that protect the thin-film solar cells from environmental damage in the long term were not commercially available. The solution features a multilayer film consisting of barrier layers, plus a covering film that is UV-resistant on the outer layer. This efficiently protects the underlying functional layers and hence the solar cells from the weather.

The weight of the thin-film modules, which are now two-thirds lighter, provides new options for photovoltaic installations. Flat roofs, which for static reasons are currently not deemed suitable for supporting the heavy, rigid solar modules, will become a possibility. The flexible modules could also be installed on vehicle roofs and laptops, reducing fuel consumption for drivers and sparing laptop users the hassle of searching for a socket.
