Post‐Deposition Photonic Curing Treatment for Improved Sb2Se3 Photovoltaic Performance
Advanced Optical Materials, EarlyView.Millisecond‐scale photonic curing overcomes the open‐circuit voltage deficit in Sb2Se3 solar cells by transforming the rear interface. This ultrafast treatment enhances crystallographic texture and smooths the absorber surface, suppressing interfacial recombination and boosting power conversion efficiency to 8.2%.
