Our perovskite solar cell technology is designed to enhance the existing photovoltaic industry. When built on top of conventional silicon solar cells in a tandem configuration, the resulting perovskite-on-silicon solar cells are at least 20% more efficient. This enhances the performance of silicon solar cells on the same footprint, enabling cost reductions that transform the economics of silicon solar energy generation.
Conventional 166 mm x 166 mm silicon bottom cell20-22% typical efficiency
Oxford PV perovskite top cell
Resulting 166 mm x 166 mm perovskite-silicon tandem solar cell could exceed 30% efficiency
Breaks through silicon’s efficiency limit, allowing more power on the same footprint
Designed to be built into standard PV solar modules to generate more power
Helps silicon module manufacturers to offer a higher-performance, differentiated product
Increased power output on the same footprint, reducing the levelised cost of energy (LCOE) of a solar installation
