The US Department of Energy's National Renewable Energy Laboratory (NREL) has confirmed Longi's achievement of a world record-breaking efficiency rating of 33.9% for a perovskite-silicon tandem solar cell.
In my very limited understanding there are too many loses between material to endpoint. The old limit used to be 35% before they made new materials so maybe we can improve the potential in future.
