WILMINGTON, Del., Aug. 21, 2014

WILMINGTON, Del., Aug. 21, 2014 /PRNewswire/ --Today DuPont filed a patent
infringement lawsuit against SunEdison and its affiliate NVT LLC in the U.S.
District Court for the District of Delaware. In its complaint, DuPont alleges
that by sourcing and using photovoltaic cells and solar modules containing
Samsung SDI Co., Ltd. (into which the former Cheil Industries Inc. merged)
front side metallization paste, SunEdison infringes DuPont's patented
tellurium paste technology. The complaint also identifies Neo Solar Power of
Taiwan as the cell manufacturer and Flextronics as SunEdison's contract
manufacturer.

"DuPont will enforce its patent rights to protect our substantial investment
in innovation to improve solar energy efficiency," said Peter Brenner, global
photovoltaic business marketing manager, Microcircuit Materials, DuPont
Electronics & Communications. "Installers and module makers like SunEdison
are responsible for ensuring that their products do not use infringing cells
or pastes. Our patented tellurium technology is available only from DuPont;
no other photovoltaic paste manufacturer has a license to use our patented
technology."
