We have used a solution-based approach to incorporate boron (B) and indium (In) dopants into the conventional SnO2 electron transport layer (ETL) to create high-performing planar perovskite solar cells (PSCs). By adding B and In in precise stoichiometric ratios to the standard SnO2 precursor solutio...
