When built on top of conventional 156 mm x 156 mm silicon solar cells, in a tandem configuration, the resulting perovskite-silicon tandem solar cells show highly improved efficiency. Significantly improving the performance of silicon solar cells on the same footprint, enables cost reductions that transform the economics of silicon solar energy generation. Our tandem solution enables + 30% combined cell efficiency Breaks through silicon’s efficiency limit, allowing more power on the same footprint Ease of integration Designed to be built into standard PV solar modules, to generate more power, critical for delivering more affordable clean energy Product differentiation Allows silicon module manufacturers the ability to offer a higher performance, differentiated product Transformed silicon solar economics Dramatically increased power output on the same footprint, reducing the levelised cost of energy (LCOE) of a solar installation Oxford PV sets world record for perovskite solar cell Our perovskite-silicon solar cell has achieved a certified 28% 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.
