Climate change has made a clean-energy, all-electric future a global imperative. Our perovskite-on-silicon solar cell delivers high efficiency at a low cost – essential for solar to replace fossil fuels, meet growing energy demand, and ultimately power an all-electric world.
Today, the mainstream solar technology – silicon – is reaching its practical and economic photovoltaic efficiency limit. Our perovskite solar cell technology will allow silicon solar cell and module manufacturers to break through the performance barrier. Significantly improving the performance of silicon photovoltaics will enable cost reductions that will transform the economics and accelerate the growth of solar energy globally.
Why perovskite photovoltaics?
Enhances the 100 GW photovoltaic industry

When built on top of conventional silicon solar cells, the resulting tandem cells can break through the silicon photovoltaic performance barrier.

High photovoltaic performance

A perovskite-on-silicon tandem cell has a theoretical efficiency limit of 43% vs 29% for silicon cells.

Wide adjustable bandgap

Ability to capture specific parts of the solar spectrum, particularly at the high-energy blue end and convert it into electricity.

Low-cost, thin-film photovoltaic solution

Widely available, low-cost source materials. Simple manufacturing processes.

Oxford PV sets world record for perovskite solar cell

Our perovskite-silicon solar cell has achieved a certified 29.52% conversion efficiency. This exceeds the highest ever performing single-junction silicon solar cell – validating the ability of perovskite to enhance the performance of silicon-based photovoltaics.
