Halide perovskites perform remarkably in optoelectronic devices. However, this exceptional
performance is striking given that perovskites exhibit deep charge-carrier traps and spatial …

Hydrogen is one of the most important energy alternatives to conventional fossil‐based fuel.
Solar energy based photocatalytic hydrogen evolution (PHE) is a salient approach to …

Halide perovskites are promising candidate materials for the next generation high‐efficiency
optoelectronic devices. Since perovskites are electronic‐ionic mixed conductors, ion …

Transport of energy carriers in solid-state materials is determined by their wavefunctions and
interactions with the environment. While quantum transport theory has predicted distinct …

Formamidinium lead iodide (FAPbI3) in its α‐phase is among the most desirable perovskite
compositions for solar cells. However, because of its transition into the yellow δ‐phase at …

Here, we demonstrate cyclopropylcarbamidine hydrochloride (CPAH) as a novel organic
halide salt to construct 2D layer for surface passivation of phase-pure FAPbI 3 film. The …

Perovskite solar cells (PSCs) have emerged as a leading photovoltaic technology due to
their high efficiency and cost-effectiveness, yet long-term stability and consistent …

Carbon-based black pigments, a widely used class of pigments, are difficult to differentiate
with the noninvasive techniques currently used in cultural heritage science. We use pump …

The determination of the semiconducting materials performance heavily relies on the
diffusion coefficient and length of the carrier. Recently, significant progress is made in …

Over the past decade, the proliferation of pulsed laser sources with high repetition rates has
facilitated a merger of ultrafast time-resolved spectroscopy with imaging microscopy. In …
