Enhanced output performance of a flexible piezoelectric energy harvester based on stable MAPbI3-PVDF composite films
Abstract
Abstract The fabrication of a piezoelectric generator (PEG) that could provide higher levels of durability and stability while delivering higher output is an ever-present goal for self-powered and wearable electronic devices. This study resulted in a PEG based on a composite film composed of methylammonium lead iodide (MAPbI3) perovskite, and poly(vinylidene fluoride) (PVDF), as a flexible polymer matrix that delivers high performance, flexibility and cost-effectiveness. These homogeneous MAPbI3-PVDF composite films with various volume factions of MAPbI3 were realized using simple solution technique, which show predominant dielectric and ferroelectric properties by varying the volume fraction of the MAPbI3. In particular, composite films containing 25 vol% MAPbI3 revealed a high dielectric constant of 56 at 1 kHz and remanent polarization of 0.83 µC/cm2. This particular PEG showed a high open-circuit voltage (Voc) of 17.8 V and a short-circuit current density (Jsc) of 2.1 µA/cm2, and the same PEG with an active layer thickness of 97.7 µm has shown an enhancement in Voc of 45.6 V and Jsc of 4.7 µA/cm2. This level of high-output power performance is sufficient for operating commercial light-emitting diodes even under finger tapping without the need of a storage device.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
