Delaware, United States [RenewableEnergyWorld.com] DuPont announced yesterday the commercialization of two new families of photovoltaic encapsulant sheets that the company expects will improve durability and efficiency of photovoltaic modules.
DuPont says the encapsulants will contribute to longer life and reduced cost-per-watt, helping system manufacturers deliver more reliable and cost-effective solar power. On a global basis, DuPont expects to nearly triple annual sales from its portfolio of photovoltaic materials to more than $1 billion by 2012.
“With these new introductions, DuPont science is helping enable the faster spread of solar power,” said William F. Weber, vice president and general manager of DuPont Packaging & Industrial Polymers. “These new encapsulant materials contribute to keeping cost-per-watt low and reducing the total cost of ownership for solar power.”
According to the company, DuPont PV5300 Series sheets are five times tougher and 100 times stiffer than materials typically used as encapsulants. Their structural properties make possible new module designs such as building-integrated photovoltaic (BIPV) tiles that can be installed on building roofs.
The company also launched DuPont PV5200 Series sheets which are designed to meet the needs of thin-film solar power generation, a fast-growing segment of the industry. They are based on polyvinyl butyral polymer technology and offer high performance in physical processing. DuPont says they enable faster, more efficient module production and longer service life.
