Anti-aging elixir for solar cells
Date:8/2/2012

Sometimes it's just a couple of cents that decide the success or failure of a technology. As long as solar power, for instance, is still more expensive than energy extracted from fossil fuels, photovoltaics will not be competitive on the broad open market. "Power generation from solar energy continues to be reliant on public subsidies this is no different in the USA than in Germany," explains Christian Hoepfner, Scientific Director of the Fraunhofer Center for Sustainable Energy Systems CSE in Cambridge, Massachusetts, USA. "If we want renewable energy to penetrate the global market over the long term, then we must ensure it gets cheaper."

There are no silver bullets to reach this target: Efficiency cannot be arbitrarily increased, and it is expensive to produce solar cells and modules. If you want to change something here, you have to solve a puzzle with many variables: Engineering teams around the world are searching for new technologies and production methods to make cells and modules cheaper, more efficient, more durable and reliable.

Silicone steady and resilient

Silicone is one of the promising materials. It is a highly unusual substance neither inorganic crystal nor organic polymer but related to both. While PV modules have been encapsulated with silicones, until now, however, they were not widely used for laminating solar modules. Lamination is a protective coating that surrounds the fragile silicon wafer. Today most manufacturers of photovoltaic cells use ethylene-vinyl acetate, or EVA for short.

In order to determine if silicone could replace the ethylene-vinyl acetate a team of experts worked together: researchers from Fraunhofer and from Dow Corning Corporation, the world's largest manufacturer of silicones used in medical technology, cosmetics, the automotive industry, paper processing and electronics. The scientists coated photovoltaic cells with liquid silicone. "When the silicone hardens, it encases
