Abstract The urgency for a sustainable mitigation of the environmental impacts caused by climate change highlights importance renewable energy technologies to fight this challenge. Perovskite solar cells (PSCs) emerge as promising alternative traditional photovoltaic (PV) due their unprecedented increase in efficiency (currently peaking at 26.95%) and long‐term stability proven successful completion industry relevant International Electrotechnical Commission (IEC) testing standards. Flexible PSCs (f‐PSCs) offer significant advantages such lightweight high power‐per‐weight ratio, mechanical flexibility, throughput roll‐to‐roll (R2R) manufacturing. These make f‐PSCs ideal implementation various applications areas, wearable electronics, portable devices, space PV, building‐ or automotive‐integrated PVs, more.

Abstract Molecular bridges with one end absorbed on the electron transport layer (ETL) and other bound to perovskite can effectively repair imperfections at ETL/perovskite interface. However, single‐layered usually coexist undesired double‐layered molecules, leaving a Van der Waals gap between them. Charge only occur via tunneling effect travel through gap, which requires forward voltage bias leads constrained charge efficiency. Herein, study designs synthesizes an imidazolium derivative ionic salt of 1,3‐dibenzyl‐2‐phenylimidazolium chloride (DPhImCl), featuring multiple aromatic side chains, form bilayered interfacial molecular mediated by π–π stacking. The reveals that DPhIm + strongly adsorbs both SnO 2 surfaces ring, while two layers respectively interact stacking benzene ring in forming bridge /perovskite This interaction promotes orderly creates hopping channels for transport, thus facilitating transfer As result, impressive device efficiency 25.90% (certified 25.27%) robust T 90 operational lifetime 1101 h n‐i‐p solar cells achieved.

Perovskite solar cells (PSCs) suffer from a quick efficiency drop after fabrication, partly due to surface defects, and can be further enhanced with the passivation of defects. Herein, is reviewed as method improve both stability PSCs, an emphasis on chemical mechanism passivation. Various molecules are utilized passivants, such halides, Lewis acids bases, amines (some result in low-dimensional perovskite), polymers. Multifunctional promising group they capable passivating multiple defects various functional groups. This review categorizes these addition considering potential limitations each type passivant. Additionally, passivants for Sn-based PSCs discussed since this has poor photovoltaic performance compared their lead-based counterpart severe Lastly, future perspectives usage addressed provide direction upcoming research practical applications.

The limited operational lifetime of quantum-dot light-emitting diodes (QLEDs) poses a critical obstacle that must be addressed before their practical application. Specifically, cadmium-free InP-based QLEDs, which are environmentally benign, experience significant degradation due to challenges in charge-carrier confinement stemming from the composition InP quantum dots (QDs). This study investigates QLEDs and provides direct evidence process. To facilitate studies, double-emission structure was designed. We employed transient electroluminescence photoluminescence for nondestructive analysis dynamics during device degradation. time-resolved emission sequence revealed changes carrier mobility within QD layer as devices degraded. Furthermore, prolonged exposure QDs population hindered radiative recombination. Our observations indicate clear QLED degradation, characterized by ligand detachment surface deterioration hole-transporting material excessive electrons. comprehensive mechanisms lays groundwork improving stability longevity, serving benchmark future research development field nanocrystal-based electroluminescent devices.

Abstract The past decade has witnessed the rapid increasement in power conversion efficiency of perovskite solar cells (PSCs). However, serious ion migration hampers their operational stability. Although dopants composed varied cations and anions are introduced into to suppress migration, impact or is not individually explored, which hinders evaluation different further application doping strategy. Here we report that a special group sulfonic (like CF 3 SO − ) successfully introduce alkaline earth ions Ca 2+ lattice compared its halide counterparts. Furthermore, with effective crystallization regulation defect passivation anions, Ca(CF 2 shows reduced PbI residue metallic Pb 0 defects; thereby, corresponding PSCs show an enhanced PCE 24.95%. Finally by comparing properties FACF , found doped significantly suppressed activation energy 1.246 eV accounts for improved stability -doped PSCs, while no obvious on trap density observed. Combining benefits this study presents method decouple effects fabricate efficient stable PSCs.
