Uniform Permutation of Quasi-2D Perovskites by Vacuum Poling for Efficient, High-Fill-Factor Solar Cells

TL;DR: In this paper, a different strategy of uniformly arranging different n-value nanoplates (PEA2MAn-1PbnI3n+1) by introducing vacuum poling treatment to enforce nucleation during crystallization is reported.
Journal ArticleDOI

Establishing charge-transfer excitons in 2D perovskite heterostructures.

TL;DR: It is reported that CTEs can be effectively formed in heterostructured 2D perovskites prepared by mixing PEA 2 PbI 4 :PEA 2 SnI 4 , functioning as host and guest components.
Journal ArticleDOI

Photoinduced Bulk Polarization and Its Effects on Photovoltaic Actions in Perovskite Solar Cells

TL;DR: A Kelvin probe force microscopy study shows that chlorine incorporation can suppress the density of charged defects and thus enhances photoinduced bulk polarization due to the reduced screening effect from charged defects, and a bias-dependent photoluminescence study indicates that increasing bulk polarization can suppress carrier recombination by decreasing charge capture probability through the Coulombic screening effect.
Journal ArticleDOI

Exploring Anomalous Polarization Dynamics in Organometallic Halide Perovskites.

TL;DR: These OMHPs present the limit of ferroelectric materials with spontaneous polarization dynamically screened by ionic and electronic carriers, which is suppressed by fast ion dynamics.
Journal ArticleDOI

Exploring spin-orbital coupling effects on photovoltaic actions in Sn and Pb based perovskite solar cells

TL;DR: In this paper, the spin-dependent photocurrent (Jsc) becomes much more prominent upon replacing Pb with Sn, increasing the spin dependence from 025% to 125% by switching the photoexcitation from linear to circular polarization.
