Abstract

Mg-doped TiO₂ nanorods were successfully synthesized from colloidal titanate by a microwave hydrothermal reaction. Use of such TiO₂ having an elevated conduction band edge as an electron extracting material for ammonium lead halide perovskite solar cells resulted in an increase of V_oc by as much as 215 mV.
