Organic halide salt passivation is considered to be an essential strategy to reduce defects in
state-of-the-art perovskite solar cells (PSCs). This strategy, however, suffers from the …

Organic solar cells (OSCs) based on nonfullerene acceptors (NFAs) have made significant
breakthrough in their device performance, now achieving a power conversion efficiency of≈ …

In the last decade, organic–inorganic hybrid lead-halide perovskites have been attracted
tremendous attentions in the photovoltaic and optoelectronic community. Especially for …

Tin (Sn)-based and mixed tin–lead (Sn–Pb) perovskites have attracted increased attention
as promising candidates for new generation lead-free perovskite and all-perovskite tandem …

Sn–Pb mixed perovskites with bandgaps in the range of 1.1–1.4 eV are ideal candidates for
single‐junction solar cells to approach the Shockley–Queisser limit. However, the efficiency …

Mixed tin–lead halide perovskites have recently emerged as highly promising materials for
efficient single-and multi-junction photovoltaic devices. This Focus Review discusses the …

The rapid relaxation of hot carriers leads to energy loss in the form of heat and consequently
restricts the theoretical efficiency of single‐junction solar cells; However, this issue has not …

Abstract Tin‐lead (Sn‐Pb) perovskite solar cells (PSCs) with near‐ideal bandgap still lag
behind the pure lead PSCs. Disordered heterojunctions caused by inhomogeneous Sn/Pb …
