Coherent two-dimensional photocurrent spectroscopy in a PbS quantum dot photocell

Two-dimensional photocurrent spectroscopy can identify coherent electronic dynamics and offers promise for studies of numerous material systems. Karki et al. now show that the method can be used to study ultrafast carrier processes in lead sulphide quantum dots, such as multiple exciton generation.

Implementing an intermittent spin-coating strategy to enable bottom-up crystallization in layered halide perovskites

Random orientation of layered crystals in 2D perovksites impedes the out-of-plnae carriers transport and hence undermines the photovoltaic perofrmance. Here, the authors discover that the crystallisation can be regulated by intermittent spin-coating strategy.

Two-dimensional electronic spectroscopy

Two-dimensional electronic spectroscopy (2DES) is an optical technique that can investigate ultrafast dynamics with femtosecond time resolution. This Primer describes the underlying physical principles behind 2DES and explains how it can be applied to study different dynamic photophysical processes.
