Quasi-two-dimensional (2D) perovskites are highly promising light-harvesting materials for commercialization of perovskite solar cells (PSCs) owing to the excellent stability. However, coexistence multiple n-value species in 2D often causes increased complexities crystallization that can negatively affect eventual photovoltaic performance. Herein, we present a binary solution based strategy via introducing nontoxic and widely accessible CH3COOH (HAc) as co-solvent preparing high-quality...
Abstract While 2D Ruddlesden‐Popper (RP) perovskites exhibit attractive opto‐electronic properties and stability for use in perovskite solar cells (PSCs), their complicated film‐forming processes often induce a non‐negligible level of defects that significantly undermine the power conversion efficiency (PCE) PSCs. Here, two organic ammonium salts with same chain length, namely monoammonium (butylammonium iodide, BAI) diammonium (1,4‐butanediamine dihydroiodide, BDAI 2 ) surface defect...
2D perovskites based on Formamidinium (FA) hold the potential for excellent stability and a broad absorption range, making them attractive materials solar cells. However, FA-based produced via one-step processing exhibit poor crystallinity random quasi-quantum wells (QWs), leading to subpar photovoltaic performance. In this study, seed-induced growth approach is introduced employing MAPbCl3 BDAPbI4 in deposition of Dion-Jacobson perovskite films. This method yields high-quality films as...

Abstract The power conversion efficiencies (PCEs) of all‐polymer solar cells (all‐PSCs) have already exceeded 17%. However, the limited absorption range an system results in significantly reduced short‐circuit current density ( J sc ), which eventually influences PCE improvement.
