Climate change has made transforming our energy economy into one that is clean, renewable, and sustainable a global imperative. Our perovskite/silicon tandem solar cell solution delivers high efficiency at a low cost, which is essential for solar to replace fossil fuels and meet growing energy demand. Our technology uses existing production routes taken from the Si industry and drastically enhances the power output with the addition of a perovskite top-cell in a tandem configuration. Supported by excellent advancements in the field of perovskite photovoltaics in recent years, we have demonstrated a certified world-record efficiency of 29.5%, which far exceeds the record Si single junction performance (26.7%) and even exceeds the physical limit of Si PV (29.3%). With this presentation, we will give a brief look at the activities at both our R&D site in England and our industrial site in Germany, where we will commence production in 2022.
