Preparation and characterization of narrow bandgap ferroelectric (K,Ba)(Ni,Nb)O3−δ films for mesoporous all-oxide solar cells
Ferroelectric (K,Ba)(Ni,Nb) ${{\rm{O}}}_{3-\delta }$ films have triggered intense studies for applications in photovoltaic device due to their efficient ferroelectric polarization-driven carrier separation and above-bandgap generated photovoltages. However, they are suffered from a challenge of prep...
