Leading with technology

We use cutting-edge science to engineer breakthrough photovoltaic technologies.

Perovskite tandem photovoltaics

We stack individual metal halide perovskite solar cells to make tandem cells. Tandems can break through the 30% conversion efficiency barrier, they can be manufactured at low cost, and they can be integrated into ultra-lightweight and flexible solar panels with up to 100 times the power-to-weight performance of conventional panels. Our perovskite tandem technology delivers abundant zero-carbon electricity for any application under the sun.
