DuPont is a leading technology supplier to the photovoltaic (PV) industry, with more than 25 years of experience in PV materials development, applications know-how, manufacturing expertise and global market access. DuPont Photovoltaic Solutions (DPVS) represents a broad and growing portfolio of innovations for the industry, developed by leveraging science from across the company, and working closely with strategic partners across the value chain. DPVS offerings are designed to increase the lifetime and efficiency of solar modules, and improve the productivity of PV module makers.

Our products are key to the manufacture of both crystalline silicon and thin film solar cells and modules. They include films, resins, encapsulation sheets, flexible substrates and conductive pastes, as well as high performance seals for solar cell manufacturing equipment.

We continue to invest in both capacity expansions to support the explosive industry growth, and the development of new innovative technologies to address different applications within the industry.

DuPont has also made a corporate commitment to have at least ten percent of its power produced by renewable energy sources by 2010, some of which will be supplied through the installation of systems with solar generation. Today, more than five percent of the company’s power is produced by renewable energy sources. DuPont has installed photovoltaic solar power systems for its R&D and business facilities in Wilmington, Del., and Taoyuan, Taiwan, and is planning additional installations in the U.S. and India, as an example of DuPont science and innovation enabling businesses and consumers to convert sunlight directly into electricity.

The company’s offering for this market provides innovative business solutions to help meet the growing demand for renewable energy technology. Through science and technology, innovative technologies from DuPont enable solar modules to run more efficiently, last longer and provide safer and more environmentally sustainable solutions, making solar possibilities into everyday realities, to provide energy for a thriving world.
