Solliance has achieved world record cell-level conversion efficiency of 13.5% and module-level aperture area conversion efficiency of 12.2% for perovskite-based photovoltaics using industrially-applicable, roll-to-roll (R2R) production processes.                         Perovskites, are perhaps, the most exciting solar energy technology to appear in recent years. They offer high efficiency from relatively simple production processes, bringing the potential for cheaper, greener energy. Moreover...
