The European Solar Test Installation (ESTI) has confirmed Longi's achievement of a world record-breaking efficiency rating of 34.6% for a perovskite-silicon tandem solar cell.
The main issue is with longevity, once they solve that, I am hopeful they will then this will dominate the Solar market completely and replace all the Silicon based single band gap panels. Even someone with relatively recent panels of 20-22% would benefit a lot from 35% panels, that is a lot of extra power in the same space.
