Solution phase synthesis of carbon quantum dots as sensitizers for nanocrystalline TiO2solar cells
Abstract
Carbon quantum dots (CQDs) have recently emerged as viable alternatives to traditional semiconductor quantum dots because of their facile and low cost synthesis, long term colloidal stability, and low environmental and biological toxicity. The compatible surface chemistry, good solubility in polar solvents and extensive optical absorption throughout the visible and near-infrared wavelength regions render CQDs as potentially useful sensitizers for photovoltaic applications. Presented herein is a new strategy for the solution phase synthesis of water-soluble, colloidally stable CQDs and a preliminary exploration of their utilization as sensitizers in nanocrystalline TiO2 based solar cells. Under AM 1.5 illumination, the Voc and FF values reach 380 mV and 64% respectively, achieving a power conversion efficiency of 0.13%.

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.
