Abstract Low-dimensional/three-dimensional perovskite heterojunctions have shown great potential for improving the performance of photovoltaics, but large organic cations in low-dimensional perovskites hinder charge transport and cause carrier mobility anisotropy at heterojunction interface. Here, we report a low-dimensional/three-dimensional that introduces strong aromatic conjugated p-i-n devices to reduce electron resistance crossing perovskite/electron extraction The π-conjugated network...
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...
Abstract Electrochemical sulfion oxidation reaction (SOR) offers a sustainable strategy for sulfion‐rich wastewater treatment, which can couple with cathodic hydrogen evolution (HER) energy‐saving production. However, the corrosion and passivation of sulfur species render inferior catalytic SOR performance, product, polysulfide, requires further acidification to recover cheap elementary sulfur.

Abstract Perovskite/organic tandem solar cells (POTSCs) have garnered significant attention due to their potential for achieving high photovoltaic (PV) performance. However, the reported power conversion efficiencies (PCEs) and fill factors (FFs) are still subpar challenges associated with charge extraction in organic bulk‐heterojunction (BHJ) energy losses interconnecting layers (ICLs).

Abstract The electron transporting layer (ETL) used in high performance inverted perovskite solar cells (PSCs) is typically composed of C 60 , which requires time‐consuming and costly thermal evaporation deposition, posing a significant challenge for large‐scale production.

Perovskite solar cells (PSCs) have emerged as a leading photovoltaic technology due to their high efficiency and cost-effectiveness, yet long-term stability consistent performance remain challenges. This perspective discusses how local structural properties, such grain boundaries intragrain defects, optoelectronic including charge transfer recombination processes, affect PSC performance, emphasizing the role of advanced imaging mapping techniques in characterizing these properties....

Abstract The combination of three-dimensional (3D) metal halide perovskite with low-dimensional (LD) in a heterojunction has shown significant potential for improving the performance solar cells (PSCs).
