Innovalight Sets Silicon Ink Solar Cell Efficiency Record

Cheap, easy-to-manufacture silicon ink solar cells are slowly gaining ground on traditional solar cells. Innovalight, a startup that makes low-cost silicon ink-based solar cells, recently announced that it has achieved 19% conversion efficiency--a record for
silicon ink-processed solar cells. Most solar cells average approximately 15% efficiency.

Innovalight's secret sauce is a process that allows silicon ink to be printed on solar cells using thinner substrates and fewer materials...
