Perovskite cell

Michael McGehee

The future鈥檚 getting brighter for solar. CU 麻豆影院 researchers have created a low-cost solar cell with one of the highest power-conversion efficiencies to date.

By layering a perovskite solar cell鈥攁 crystal structure designed to harvest higher energy photons鈥攐n top of a silicon solar cell, the silicon cell can capture more photons in the infrared part of the spectrum, which is what we feel as heat.

It has surpassed the maximum efficiency of a silicon-only solar cell and 鈥渨e believe it can take us over 30% efficiency and that it can be stable,鈥 said Michael McGehee, a professor in the Department of Chemical and Biological Engineering.

With the solar power market growing around 30% per year, this technology could make solar a more effective and affordable option for eco-conscious homeowners and businesses.
