New coatings for solar panels

DuPont has announced the commercialization of two new families of coatings, which should improve the lifetime and efficiency of solar panels.

According to the U.S. firm, the new series PV5300 and PV5200 are able to provide long term protection for the most sensitive photovoltaic modules such as solar cells. The protective films would be five times stronger and 100 times more rigid than the materials normally used.

"These new materials will help reduce the cost per watt of solar cells. We expect growth of over 25% per year over the next five years for these types of materials, due to the strong growth in facilities Photovoltaic globally. " said William F. Weber, Vice President of the group.

The company also launched the PV5200 series designed to meet the needs of solar technologies in thin layers, a fast-growing segment in the industry. It is based on polyvinyl butyral polymers providing high performance in the physical treatment.

DuPont plans to almost triple the annual turnover of his business "photovoltaic materials" of more than 1 billion by 2012.
