The perovskite-silicon tandem

  • Conventional 156 mm x 156 mm silicon bottom cell
    20-22% typical efficiency

  • Oxford PV perovskite top cell

  • Resulting 156 mm x 156 mm perovskite-silicon tandem solar cell
    Could 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-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

Allows silicon solar cell and module manufacturers to break through today's efficiency limits.

Ease of integration

Designed to be retrofitted into existing silicon solar cell and module fabrication lines using standard equipment, to increase production line capacity.

Product differentiation

Allows silicon solar cell and module manufacturers 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.
