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.
This is interesting but issue with Perovskites is not efficiency per say, but it is degradation. It is a cool tech but their lifetime is measured in months and not decades. Here’s one study for instance. Perovskites might be where the tech is going but there are still major hurdles to overcome.
