PV materials firm, DuPont filed a patent infringement lawsuit against SunEdison and its affiliate NVT LLC in the US District Court for the District of Delaware over the use of its tellurium paste technology.

The claim may target major PVEP, SunEdison but the company claims that former Cheil Industries, now part of Korean-based Samsung SDI was the paste supplier to Taiwan-based solar cell producer, Neo Solar Power (NSP) that supplied cells to module assembly sub-contractor to SunEdison, Flextronics. SunEdison outsources all its PV module needs.

“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.”

DuPont had previously filed a patent infringement case against Heraeus, which was later settled out of court.

The solar tracker market continues to mature at breakneck speed, with designs and component selections becoming ever-more complex in the pursuit of better project economics. But a more simplistic design could deliver a triple benefit of lower Capex, EPC and Opex costs. This webinar will set out the ideal single axis tracker design for utility-scale solar farms. The design leapfrogs from decades of experience, with a comprehensive understanding and attention to the three cost structures of Capex, EPC and Opx. Sun and Steel Solar has prototyped a single axis tracker designed to deliver up to US$0.03/W in real savings compared to existing single axis trackers on the market. That’s US$30 million for every gigawatt deployed.
