Graphene-CsPbBr3 quantum dots photodetectors with high responsivity

四川大学学报. 自然科学版, 2021
All-inorganic perovskites, such as CsPbX3 (X = Cl, Br, I), are gaining increasing attention due to their outstanding optoelectronic properties, especially their higher thermal stability comparing with organic-inorganic hybrid perovskites. However, CsPbX3-

Influence of Radiation on the Properties and the Stability of Hybrid Perovskites

Advanced Materials, 2017
AbstractOrganic–inorganic perovskites are well suited for optoelectronic applications. In particular, perovskite single and perovskite tandem solar cells with silicon are close to their market entry. Despite their swift rise in efficiency to more than 21%, solar cell lifetimes are way below the needed 25 years.

Sensing of explosive vapor by hybrid perovskites: Effect of dimensionality

APL Materials, 2020
Lead halide perovskites are very promising materials for many optoelectronic devices. They are low cost, photostable, and strongly photoluminescent materials, but so far have been little studied for sensing. In this article, we explore hybrid perovskites

From Behavior to Dynamics: Decoding Carrier Roles in Cu‐based Photocathodes for Solar‐Driven CO2 Reduction

Advanced Materials, EarlyView.
The performance of Cu‐based photocathodes in photoelectrochemical CO2 reduction is not governed by catalytic sites alone, but by the dynamic journey of photogenerated carriers. This review decodes how carrier generation, recombination, transport, accumulation, extraction, and electrolyte coupling shape catalytic activity, selectivity, and stability ...

Lattice expansion of hybrid perovskite inhibits halogen interstitial generation and enhances solar cell performance

Nature Communications
One of the primary challenges for halide perovskite technology lies in its instability. Water is a ubiquitous environmental factor known to induce lattice expansion to perovskite. Lattice expansion has been proven beneficial to perovskite solar cell, but
