Machine-Learning-Guided Optimization of Rapid-Lamp-Annealed Hematite Photoanodes for Solar Water Splitting
Hematite (α-Fe2O3) photoanodes for solar water splitting suffer from poor charge transport and significant sample-to-sample irreproducibility. Here we show that rapid lamp annealing (RLA), in which a graphite susceptor enables rapid volumetric heating, produces hematite films with substantially higher and more reprod...
