Innovalight Silicon Ink Solar Cells Achieve 19% Conversion Efficiency

Innovalight, Inc. announced that the company has achieved a new record of 19% conversion efficiency with silicon ink processed solar cells. The conversion efficiency of a solar cell is the proportion of sunlight energy that a cell converts to electrical energy.

The Fraunhofer Institute for Solar Energy Systems (ISE) in Germany, an official independent solar cell testing center also measured the results on industry standard size cells made by Innovalight.

Innovalight’s proprietary platform, Cougar™ offers a readily transferable process to crystalline silicon solar cell manufacturers that allows them to improve solar cell performance, reduce cost and boost output capacity by adding a simple step to already installed manufacturing lines. The opportunity is significant – this year close to four billion crystalline wafers will be processed into solar cells, according to Navigant Consulting, Inc., a leading solar industry research firm.

"We continue to push toward our goal of delivering over 20 percent conversion efficiency to our customers," said Homer Antoniadis, Chief Technology Officer at Innovalight. "Our patented solar cell process with silicon ink is simple and optimized for use with silicon wafers and widely adopted industry printing tools," he added.

Innovalight is currently working with several solar cell manufacturing companies and is ramping production of silicon ink in Sunnyvale, California.
