Oxford PV will commercially launch a perovskite tandem solar cell that is integrated with standard silicon solar cells in mid-2021 and it will dramatically to improve solar cell performance. They will be built into industry-standard solar PV panels, the tandem cells significantly increase power output and provide more affordable clean energy. In 2018, they had a tandem cell with 28% solar conversion efficiency versus about 22% for regular solar cells. Oxford PV believes they can reach over 40% solar conversion efficiency.

A perovskite-on-silicon tandem cell has a theoretical efficiency limit of 43% vs 29% for silicon cells. The 2021 commercial product will likely reach 30% energy conversion efficiency.

Perovskites can be printed using an inkjet printer.

Perovskite could be sprayed or rolled onto flexible surfaces. Semitransparent solar coatings will be wrapped around whole buildings.

Transparent high efficiency, spray-on solar could added all over every car. Windows could generate solar power. Doubling the area of surfaces for generating power and doubling the efficiency would enable four times the energy generation.
