California, United States [RenewableEnergyWorld.com] Innovalight Inc announced that the company has been awarded a key patent for the manufacturing of crystalline wafer solar cells with silicon ink. Entitled “Methods of forming multi-doped junctions on a substrate,” U.S. Patent No. 7,615,393 was issued in one year, far less than the three year average for patents. The patent covers a process for the commercial manufacture of high efficiency selective emitter solar cells with silicon ink.
Innovalight’s proprietary nanotechnology-based silicon ink and processing technologies allow crystalline silicon solar cell manufacturers to boost output capacity and solar cell performance, as well as reduce costs with a simplified additional step to already installed manufacturing lines.
“This is a great accomplishment for Innovalight, and it’s a true success in the DOE’s PV Technology Incubator Program,” said Martha Symko-Davies, senior program manager at U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). “Innovalight was awarded a subcontract of $3 million through NREL, funded by the DOE in April 2009.”
Innovalight recently announced the company raised $18 million in additional capital. This new round of capital will be used to expand the company’s proprietary silicon ink production for customers. The series D financing was led by EDB Investments (EDBI) of Singapore.
The company has a development roadmap to ultimately bring conversion efficiencies of solar cells to over 20% using its platform for silicon ink and processing technologies. Innovalight already has over 60 patents filed for silicon ink and high efficiency solar cells using silicon ink processes.
