Efficient Solution-Processed Photovoltaic Cells Based on an Anthradithiophene/Fullerene Blend
Abstract
We report photovoltaic cells based on solution-processed blends using a novel anthradithiophene derivative as the donor and a fullerene derivative as the acceptor. Solvent vapor annealing of these blends leads to the formation of spherulites, which consist of a network of anthradithiophene crystallites dispersed in an amorphous matrix composed primarily of fullerene. We observe a direct correlation between coverage of a device with spherulites and its performance. Devices with 82% spherulite coverage reach a power conversion efficiency of 1%, which makes them one of the highest performing solution-processed small molecule photovoltaic cells to date.

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.
