Efficient Transport

Ferroelectricity can lead to creation of channels for efficient transport, however it is unlikely to explain the high open-circuit voltage (VOC), typical of high performance perovskite solar cells.

Mg-doped TiO2 nanorods were 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 a marked improvement of Voc.

We show that trapped electrons recombine with free holes unexpectedly slowly, on microsecond time scales, relaxing the limit on obtainable open circuit voltage.
