In situ observation of picosecond polaron self-localisation in α-Fe2O3 photoelectrochemical cells
The efficiency of Hematite (α-Fe2O3) photo-anodes is thought to be limited by ultrafast lattice distortions or polarons. Here, we use an optical-control method with photocurrent detection to track small polarons in real time and demonstrate that they impact photoelectrochemical cell activity
