CH3NH3Cl-Assisted One-Step Solution Growth of CH3NH3PbI3: Structure, Charge-Carrier Dynamics, and Photovoltaic Properties of Perovskite Solar Cells

Zhao, Yixin, Zhu, Kai·2014·The Journal of Physical Chemistry C

Abstract

We demonstrate a novel one-step solution approach to prepare perovskite CH 3 NH 3 PbI 3 films by adding CH 3 NH 3 Cl (or MACl) to the standard CH 3 NH 3 PbI 3 precursor (equimolar mixture of CH 3 NH 3 I and PbI 2 ) solution. The use of MACl strongly affects the crystallization process of forming pure CH 3 NH 3 PbI 3, leading not only to enhanced absorption of CH 3 NH 3 PbI 3 but also to significantly improved coverage of CH 3 NH 3 PbI 3 on a planar substrate. Compared to the standard one-step solution approach for CH 3 NH 3 PbI 3, using MACl improves the performance of CH 3 NH 3 PbI 3 solar cells from about 2% to 12% for the planar cell structure and from about 8% to 10% for the mesostructured device architecture. Although we find no significant effect of using MACl on charge transport and recombination in mesostructured perovskite cells, the recombination resistance for planar cells increases by 1–2 orders of magnitude by using MACl. These results suggest that this new one-step solution approach is promising for controlling CH 3 NH 3 PbI 3 growth to achieve high-performance perovskite solar cells.

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.
