Understanding the Role of Ion Migration in the Operation of Perovskite Light-Emitting Diodes by Transient Measurements
ACS APPLIED MATERIALS & INTERFACES, 12(43), 48845–48853.
author keywords: ion migration; perovskite light-emitting diodes; transient electroluminescence; transient current; device physics; charge injection
TL;DR:
A combined analysis of both charge injection and recombination dynamics shows that the slow response of the efficiency is attributed to enhanced charge injection facilitated by ion migration, which leads to an increased carrier density favoring bimolecular radiative recombination.

Morphological-Electrical Property Relation in Cu(In,Ga)(S,Se)(2) Solar Cells: Significance of Crystal Grain Growth and Band Grading by Potassium Treatment
SMALL, 16(48).
author keywords: average domain spacing; band grading; CIGS solar cell; electron diffusion length; solution process
TL;DR:
A unique potassium treatment method is utilized to improve the selenium uptake judiciously, enhancing grain sizes and forming a wider bandgap minimum region, which has led to a linearly increasing electron diffusion length and carrier lifetime with increasing the grain size of the CIGS film, which is a critical achievement for enhancing photocurrent yield.
