Abstract
Ferroelectric photovoltaic devices were assembled by direct stacking of bismuth ferrite (BFO) thin film with titanium dioxide (TiO2) thin film deposited on fluorine tin oxide (FTO) substrates. An enhanced short-current density of 4.06 mA/cm2 was received. The conductive atomic force microscopy (CAFM) confirms one order of magnitude increase on the collecting currents after coating of TiO2 on BFO thin film, majorly contributing from the interfaces among TiO2 and BFO particles. The ferroelectric photovoltaics generate an open-circuit voltage (VOC) of 1.66 V and a power conversion efficiency (PCE) of 4.18 %, benefiting from the enhanced conductivity of the thin film.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
