Perovskite solar cells (PSCs) offer low costs and high power conversion efficiency. However,
the lack of long-term stability, primarily stemming from the interfacial defects and the …

Wide-bandgap (WBG) perovskite solar cells (PSCs) attract intensive attention because of
their high tandem compatibility and versatile application scenarios. However, severe …

The planar triple‐layer hole transport layer (HTL)‐free carbon‐based perovskite solar cells
(C‐PSCs) have outstanding advantages of low cost and high stability, but are limited by low …

Abstract 2D‐3D tin‐based perovskites are considered as promising candidates for achieving
efficient lead‐free perovskite solar cells (PSCs). However, the existence of multiple low …

Two-dimensional (2D) perovskites have been widely adopted for improving the performance
and stability of three-dimensional (3D) metal halide perovskite devices. However, rational …

Metal contacts are an extremely important part of photovoltaic devices, since they might
decrease device stability, or underperform in their function of current extraction. In the case …

This research delves into the effects of 2D layers on the functionality of 3D perovskite using
lock‐in amplifier‐based in situ surface photovoltage (SPV) and its phase spectroscopy, with …

We fabricated MAPbI3 perovskite thin films with ZnO on a glass substrate, in which a
passivation layer (Phenethylammonium iodide (PEAI); p‐methoxyphenethylammonium …
