- Additional information
- We show that organic cations only remain aligned for a very short period of time (less than 3 picoseconds) and thus refutes the presence of long-lived (anti-) ferroelectric domains in lead hybrid perovskite solar cells. The work was highlighted in Nature Materials Features (https://doi.org/10.1038/s41563-018-0072-y), as an insightful study for the fundamental understanding of the potential photovoltaic material. This work was also presented as part of a keynote address at ChinaNano 2019.
