Perovskite solar cells have demonstrated low non‐radiative voltage losses and open‐circuit
voltages (VOCs) that often match the internal voltage in the perovskite layer, ie the quasi …

Outstanding optoelectronic properties of mixed tin‐lead perovskites are the cornerstone for
the development of high‐efficiency all‐perovskite tandems. However, recombination losses …

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 …

Flexible perovskite solar cells (F-PSCs) are increasingly being recognized for their high
specific power density and mechanical flexibility. However, the feasibility of large-scale …

Defects in perovskite films and the suboptimal interface contact largely limit the performance
and stability of inverted perovskite solar cells (PSCs). A simple surface post‐treatment with N …

Abstract Narrow-bandgap mixed Sn-Pb perovskite solar cells (PSCs) have showcased great
potential to approach the Shockley-Queisser limit. Nevertheless, the practical application …

Tin–lead (Sn–Pb) perovskite solar cells (PSCs) hold considerable potential for achieving
efficiencies near the Shockley–Queisser (S–Q) limit. Notably, the inverted structure stands …
