Global Solar Joins Dow in Solar America Initiative to Help Deliver Hi-tech, Thin-film BIPV Products for Building Construction, Including Flexible Solar Shingles TUCSON, Ariz.--(BUSINESS WIRE)--Global Solar Energy, a solar industry leader that manufactures highly-efficient thin-film solar cells for glass modules or flexible material products, today announced Dow Building Solutions, a business unit of The Dow Chemical Company, has invited Global Solar to participate in its U.S. Department of Energy Solar America Initiative (SAI) project to help create innovative building integrated photovoltaic (BIPV) products. As a part of its SAI program, Dow is creating a flexible solar roof shingle, and has made Global Solar a key team member in its development. “We are collaborating with Global Solar Energy because throughout our search for a solar material provider, it was the only company able to supply a qualifying flexible Copper Indium Gallium diSelenide (CIGS) material that meets our needs and the requirements of the SAI,” said Bob Cleereman, senior director of Solar & Structural Technology with Dow Building Solutions. “CIGS has proven to be the most efficient, cost-effective thin-film technology for BIPV applications, and by teaming up with Global Solar we are working with an industry leader. Global Solar is the only company in full-scale production of CIGS cells on flexible substrates, and has achieved a record-setting average 10 percent solar cell efficiency, meeting SAI’s requirements.” The SAI is comprised of companies, laboratories, universities and non-profit organizations. As part of the initiative, Dow is participating in the Technology Pathway Partnership, which was designed to accelerate the commercialization of U.S.-produced solar photovoltaic (PV) systems. Global Solar Energy replaced Dow’s original PV material provider in this program.
