Wide-bandgap (WBG) perovskites have attracted considerable attention due to their adjustable bandgap properties, making them ideal candidates for top subcells in tandem solar cells (TSCs). However, WBG often face challenges such as inhomogeneous crystallization and severe nonradiative recombination loss, leading high open-circuit voltage (V

Abstract Recently, mixed‐halide inorganic CsPbI 3− x Br perovskite solar cells (PSCs) have had a rapid advancement, which offers balanced efficiency, stability, tunable bandgap, and potential for indoor photovoltaic applications. Despite these advantages, significant challenges remain in the phase segregation phenomena, trap state density, absorption range limitations. This review presents an analysis of crystal electronic structure optical properties , as well in‐depth look at high‐quality film preparation, inhibition solutions, interface engineering, highlighting critical role modification performance PSCs. Furthermore, how PSCs can be strong candidates photovoltaics because their adjustable bandgap that enables them to better match notable strength stability is discussed. Finally, provides perspectives address development bottlenecks inspires future research prospects concerning

Perovskite/organic tandem solar cells (POTSCs) are gaining attention due to their easy fabrication, potential surpass the S-Q limit, and superior flexibility. However, low power conversion efficiencies (PCEs) of wide bandgap (Eg) perovskite (PVSCs) have hindered development. This work presents a novel effective mixed-cation passivation strategy (CE) passivate various types traps in wide-Eg perovskite. The complementary effect 4-trifluoro phenethylammonium (CF3 -PEA+ , denoted as CA+ ) ethylenediammonium (EDA2+ EA2+ reduces both electron/hole defect densities non-radiative recombination rate, resulting record open-circuit voltage (Voc PVSCs (1.35 V) high fill factor (FF) 83.29%. These improvements lead PCE 24.47% when applied fabricated POTSCs, highest date. Furthermore, unencapsulated POTSCs exhibit excellent photo thermal stability, retaining over 90% initial after maximum point (MPP) tracking or exposure 60 °C for 500 h. findings imply that synergic surface passivators is promising achieve high-efficiency stable corresponding POTSCs.

Light-induced phase segregation is one of the main issues restricting efficiency and stability wide-bandgap perovskite solar cells (WBG PSCs). Small organic molecules with abundant functional groups can passivate various defects, therefore suppress ionic migration channels for segregation. Herein, a series pyridine-derivative isomers containing amino carboxyl are applied to modify surface. The amino, carboxyl, N-terminal pyridine in all these interact undercoordinated Pb

Abstract Wide‐bandgap (WBG) perovskite solar cells (PSCs) are recognized as promising candidates for diversified photovoltaics (PVs), such tandem devices, indoor PVs, and semitransparent building‐integrated PVs. However, these WBG perovskites made from a mixed‐halides strategy suffer severe phase segregation under continuous illumination, leading to exacerbated non‐radiative recombination, consequently decreased open‐circuit voltage efficiency. In this review, the generation reversal processes of in meticulously introduced. Additionally, major characterization techniques presented. A detailed summary recent progress enhancing photostability PSCs through various strategies is provided. These primarily concentrate on composition regulation, crystallization modulation, inhibition ion migration, strain regulation. Finally, perspectives potential directions carefully discussed promote further development high‐efficiency photostable PSCs.
