Rena Technologies GmbH claimed that it has discovered a widespread infringement of his water cap. The patent covers the United States (US8685864B2), China (CN102754198B) and India (3496chenp2012).
The maker of German solar equipment said that evidence from the United States and India indicates that mainly Chinese suppliers advertise, build and distribute devices that enable solar cells manufacturers to perform compulsory single-side etchings in passivated emitter back contact (PERC) SOLARCELLENT Passivated Passivated Passivated. None of the companies have identified that, according to them, infringes his patent.
Rena Technologies said in an online statement that it delivers the patent of the German Schmid Group through a Cross-Licensing agreement, so that both companies are granted worldwide rights to use technology. Due to the scale of infringement, Rena Technologies is now planning to start legal proceedings, mainly in the United States and India.
“We take the protection of our intellectual property very seriously,” says Peter Schneiadewind, CEO of Rena Technologies. “The unauthorized use of patented technology brings our innovative power and competitiveness in a competitive way.”
The patent is process-based, so legal steps can extend to manufacturers of solar cells that, according to the company, use non-graduate systems. Solar cells produced in violation of the patent also run a high risk of seizure worldwide, so that companies involved in their use or resale are exposed to significant legal and financial risks, it added.
In April, Rena Technologies collaborated with the Solar cell and module manufacturer Premier Energies based in India to promote process innovations for N-type solar cells and to develop wet chemistry techniques for Tandem solar cells of the next generation. They said they want to stimulate cell performance, increase production supply and reduce the CO2 footprint in the production of solar cells.
