We demonstrate an InP heterojunction solar cell employing an ultrathin layer (∼10 nm) of amorphous TiO<sub>2</sub> deposited at 120 °C by atomic layer deposition as the transparent electron-selective contact. The TiO<sub>2</sub> film selectively extracts minority electrons from the conduction band of p-type InP while blocking the majority holes due to the large valence band offset, enabling a high maximum open-circuit voltage of 785 mV. A hydrogen plasma treatment of the InP surface drastically ...[more]
