Innovalight Hits 19% Efficiency With Silicon Ink Solar Cells

Innovalight Inc. announced that the company has achieved a new record of 19 percent 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 company said.

“We continue to push toward our goal of delivering over 20 percent conversion efficiency to our customers,” said Homer Antoniadis, CTO 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.

Dr. Antoniadis will present these results at the 2010 SNEC 4th International Photovoltaic Power Generation Exhibition and Conference which will take place from May 5-7 in Shanghai, China.

Innovalight is currently working with several solar cell manufacturing companies and is ramping production of silicon ink in Sunnyvale, California. In February, the company was awarded a key patent by the US patent and trademark office for the manufacturing of crystalline wafer solar cells with silicon ink. Innovalight has filed for over 60 patents for silicon ink and high efficiency solar cells using silicon ink processes.
