When built on top of conventional silicon solar cells, the resulting tandem cells can break through the silicon photovoltaic performance barrier.
A perovskite-on-silicon tandem cell has a theoretical efficiency limit of 43% vs 29% for silicon cells.
Ability to capture specific parts of the solar spectrum, particularly at the high-energy blue end and convert it into electricity.
Widely available, low-cost source materials. Simple manufacturing processes.
Our commercial-sized perovskite-on-silicon tandem solar cell holds the world-record efficiency of 26.8%, as certified by Fraunhofer ISE. (See ‘Solar cell efficiency tables (Version 60)’, by Martin Green et al.) We have a clear roadmap to take our technology beyond 30% efficiency.
Our perovskite-on-silicon solar cell has achieved a certified 29.52% conversion efficiency. This validates the ability of perovskite to enhance the performance of silicon-based photovoltaics.
