Solar cells (PSCs) with quasi‐2D Ruddlesden–Popper perovskites (RPP) exhibit greater
environmental stability than 3D perovskites; however, the low power conversion efficiency …

Inverted pin structure perovskite solar cells (PSCs) have attracted considerable attention in
consideration of high-efficiency, long-term stability, and cost reduction, which represent the …

The defects at the interface of the SnO2 electron transport layer (ETL) and the perovskite
absorber, as the charge-carrier recombination centers, play an important role in determining …

Organic–inorganic perovskite solar cells, as a representative of the new generation of solar
cells, have made satisfactory advancements in development over the past few years …

Hybrid organic–inorganic perovskite (HOIP) stability is affected by defects and moisture
permeation. One strategy to overcome the latter is to use organic passivators, the choice of …

Coating the perovskite layer via a two-step method is an adaptable solution for industries
compared to the anti-solvent process. But what about the impact of unreacted PbI2? Usually …

Defects as non-radiative recombination centers hinder the further efficiency improvements of
perovskite solar cells (PSCs). Additive engineering has been demonstrated to be an …

Solution processed perovskite films usually exhibit numerous defect states on the surfaces
of the films. Here in this work, oxalic acid (H2C2O4), which has two C= O groups, is selected …

Abstract Three indeno [1, 2‐b] quinoxaline‐based passivators (CQs) with different
functionalities including ketone, malononitrile, nitrile, and amine were prepared and used as …
