Enhanced tandem solar cells set new standard in converting light into electricity

A collaboration between U of T Engineering and King Abdullah University of Science and Technology has created two-layered solar cells that successfully combine traditional silicon with new perovskite technology .

Researchers from University of Toronto Engineering and King Abdullah University of Science and Technology (KAUST) have overcome a key obstacle in combining the emerging solar-harvesting technology of perovskites with the commercial gold standard — silicon solar cells. The result is a highly efficient and stable tandem solar cell, one of the best-performing reported to date.
“Today, silicon solar cells are more efficient and less costly than ever before,” says Professor Ted Sargent (ECE), senior author on a new paper published today in Science. “But there are limits to how efficient silicon can be on its own. We’re focused on overcoming these limits using a tandem (two-layer) approach.”

The device combines industry standard silicon manufacturing with new perovskite technology.
