Innovalight Silicon Inks Boost Solar Cell Efficiency to Record-Breaking 19%
In order for solar energy to be truly competitive with current carbon emitting resources, it needs to be more efficient, cost-effective, and affordable. Innovalight’s introduction of its silicon ink processes solar cells may move the solar energy industry closer to those important goals.
The second most abundant element on Earth, silicon is a non-toxic semi-conductor that has been used for many years in the transistor, solar cell, and diode industries. Its major drawback has been cost; pure silicon is expensive to process. Using silicon in a liquid ink form, however, can greatly reduce that cost - especially since Innovalight’s proprietary process can easily be integrated into existing solar cell manufacturing lines. The process also improves the efficiency of crystalline-silicon solar cells to a new record of 19%.
Innovalight is working with several cell-manufacturing companies and increasing its production of silicon ink. The Sunnyvale, CA company also has a fully equipped 10MW cell-manufacturing pilot line where potential customers can see the silicon ink process in action as well as research and testing labs.
If Innovalight's silicon ink technology proves effective, it may be a welcome shot in the arm to the solar energy industry.
