Resulting 156 mm x 156 mm perovskite-silicon tandem solar cellCould exceed 30% efficiency
Our solid-state, thin-film perovskite solar cell technology is designed to enhance the existing $183 billion photovoltaic industry. When built on top of conventional 156 mm x 156 mm silicon solar cells, in a tandem configuration, the resulting perovskite-on-silicon tandem solar cells show highly improved efficiency. This significantly enhances the performance of silicon solar cells on the same footprint, enabling cost reductions that transform the economics of silicon solar energy generation.
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, critical for delivering more affordable clean energy
Allows silicon module manufacturers the ability to offer a higher performance, differentiated product
Dramatically increased power output on the same footprint, reducing the levelised cost of energy (LCOE) of a solar installation
Our perovskite-on-silicon solar cell has achieved a certified 29.52% conversion efficiency – validating the ability of perovskite to enhance the performance of silicon-based photovoltaics.
