Further enhancing the performance and stability of inverted perovskite solar cells (PSCs) is crucial for their commercialization. We report that functionalization multication halide interfaces with an organometallic compound, ferrocenyl-bis-thiophene-2-carboxylate (FcTc2), simultaneously enhanced efficiency PSCs. The resultant devices achieved a power conversion 25.0% maintained >98% initial after continuously operating at maximum point 1500 hours under simulated AM1.5 illumination....
P-i-n geometry perovskite solar cells (PSCs) offer simplified fabrication, greater amenability to charge extraction layers, and low-temperature processing over n-i-p counterparts. Self-assembled monolayers (SAMs) can enhance the performance of p-i-n PSCs but ultrathin SAMs be thermally unstable. We report a robust hole-selective layer comprised nickel oxide (NiOx) nanoparticle film with surface-anchored (4-(3,11-dimethoxy-7H-dibenzo[c,g]carbazol-7-yl)butyl)phosphonic acid (MeO-4PADBC) SAM...

Robust contact schemes that boost stability and simplify the production process are needed for perovskite solar cells (PSCs). We codeposited hole-selective while protecting to enable deposition of SnO x /Ag without use a fullerene. The , prepared through atomic layer deposition, serves as durable inorganic electron transport layer. Tailoring oxygen vacancy defects in led power conversion efficiencies (PCEs) >25%. Our devices exhibit superior over conventional p-i-n PSCs, successfully...
Achieving rational control over chemical and energetic properties at the perovskite/electron transport layer (ETL) interface is crucial for realizing highly efficient stable next‐generation inverted perovskite solar cells (PSCs). To address this, we developed multifunctional ferrocene (Fc)‐based interlayers engineered to exhibit adjustable passivating electrochemical characteristics. These are designed minimize non‐radiative recombination and, modulate work function (WF) uniformity of...
Perovskite-based tandem solar cells (PTSCs) are promising for achieving higher efficiency limits, making them candidates energy supply. However, the commercialization in complex scenarios necessitate extreme stability and reliability of devices, particularly ambient conditions. Herein, use a high-efficiency air-stable quaternary all-polymer bulk heterojunction (BHJ) is pioneered to optimize spectral absorption, facilitate charge transport, suppress exciton recombination, resulting 18.0%...
Abstract Solution‐processed photodetectors have emerged as promising candidates for next‐generation of visible‐near infrared (vis–NIR) photodetectors. This is attributed to their ease processing, compatibility with flexible substrates, and the ability tune detection properties by integrating complementary photoresponsive semiconductors. However, limited performance continues hinder further development, primarily influenced difference charge transport between perovskite organic In this work,...
