Synergistic defect state modulation and charge carrier dynamics in cerium (Ce) doped Sb2Se3 thin films for visible-NIR photodetectors

Performance enhancement of Cu(In,Ga)Se2 solar cells through inter-facial and bandgap engineering: a combined experimental and numerical approach

Tuning the Charge-Transport Properties of CeTiO₃ Thin Films through Controllable Phase Transformations Induced by the JNSP Technique

CeTiO3 thin films were synthesized by jet nebulizer spray pyrolysis (JNSP) at substrate temperatures of 350, 400, and 450 °C to investigate temperature-dependent structural, optical, morphological, and electrical properties for photodiode applications. X-ray diffraction analysis confirmed temperature-induced phase evol...

Surface Defect-Passivation in SnO2 Electron Transport Layers by Caesium Iodide for High-Carrier Dynamics in Perovskite Solar Cells

Perovskite solar cell (PSC) performance is critically limited by surface defects and interfacial energy losses at the tin oxide (SnO2) electron transport layer (ETL). This study investigates the surface modification of SnO2 using cesium iodide (CsI) and cesium fluoride (CsF) to understand their influence on perovskite...

Nd-induced defect engineering in Ba3Fe2WO9 triple perovskite: controlling phase competition, magnetic crossover, and visible-light photocatalysis

Hexagonal triple-perovskites offer a defect-sensitive platform in which magnetism and photoactivity are tuned by the interplay among local coordination, strain, and oxygen non-stoichiometry. Here, we report the synthesis of Nd-substituted Ba3Fe2WO9via solid-state reaction and the structure–property correlations using d...

Effect of annealing and temperature on the electrical characterization of InSe/GaSe heterojunction photodiodes fabricated by the SILAR method

Synergistic optimization of CdS quantum dot-sensitized TiO2 electron transport layer and annealing conditions for enhanced efficiency in perovskite solar cells

The electron transport layer (ETL) plays a critical role in facilitating charge transport and influencing the overall performance of perovskite solar cells (PSCs). Titanium dioxide (TiO₂), owing to its favorable band alignment and chemical stability, remains the most commonly employed ETL. However, it suffers from limi...
