Solution-Phase Synthesis of SnSe Nanocrystals for Use in Solar Cells
Abstract
Nanocrystals of phase-pure tin(II) selenide (SnSe) were synthesized via a solution-phase route employing stoichiometric amounts of di-tert-butyl diselenide as a novel and facile selenium source. The direct band gap of the resulting nanocrystals (E(g) = 1.71 eV) is significantly blue-shifted relative to the bulk value (E(g) = 1.30 eV), a likely consequence of quantum confinement resulting from the relatively small average diameter of the nanocrystals (mu(D) < 20 nm). Preliminary solar cell devices incorporating SnSe nanocrystals into a poly[2-methoxy-5-(3',7'-dimethyloctyloxy)-1,4-phenylenevinylene] matrix demonstrate a significant enhancement in quantum efficiency and short-circuit current density, suggesting that this earth-abundant material could be a valuable component in future photovoltaic devices.

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.
