Anisotropic carrier transport and deep-level defect of antimony selenosulfide (Sb2(S,Se)3) absorber are two vital auses restraining the photovoltaic performance this emerging thin-film solar cell. Herein, chelate engineering is proposed to prepare high-quality Sb2(S,Se)3 film based on hydrothermal deposition approach, which realizes desirable passivated defects by using tetrahedral PO4 3- ion in dibasic sodium phosphate (Na2HPO4, DSP). The Lewis structure, one hand form [(SbO)3(PO4)] chelate, can adsorb polar planes cadmium sulfide (CdS) layer, promoting heterogeneous nucleation, other hand, inhibits horizontal growth (Sb4S(e)6)n ribbons due size effects, thus achieving [hk1] orientation. Moreover, introduction effectively passivates antisite SbS1. These synergistic effects have improved reduced non-radiative recombination absorber. Consequently, DSP-modified device efficiency increases from 8.59% 10.67%.

Hybrid nanocellulose material as an adsorbent to remove reactive yellow 2 dye

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Авг. 29, 2024

Textile dyes are frequently disposable in aqueous effluents, making it difficult to remove them from industrial effluents before their release natural waters. This paper deals with the fabrication of cellulose-based adsorbents by reacting nanocelulose crystalline (nanocel) N-[3-(trimethoxysilyl)propyl]ethylenediamine (TMSPEDA), forming hybrid (silylpropyl)ethylenediamine@nanocellulose (SPEDA@nanocel), which was employed as adsorbent for uptake reactive yellow 2 dye (RY-2) effluents. Characterisation SPEDA@nanocel carried out using FTIR, SEM-EDS, XRD, TGA, surface area, pH

Abstract Antimony selenosulfide (Sb 2 (S,Se) 3 ) has obtained widespread concern for photovoltaic applications as a light absorber due to superior photoelectric features. Accordingly, various deposition technologies have been developed in recent years, especially hydrothermal method, which achieved great success. However, device performances are limited with severe carrier recombination, relating the quality of and interfaces. Herein, bulk interface defects simultaneously suppressed by regulating heterogeneous nucleation kinetics barium dibromide (BaBr introduction. In details, Br adsorbs dopes on polar planes cadmium sulfide (CdS) buffer layer, promoting exposure nonpolar CdS, facilitates favorable growth [hk1]‐Sb films possessing crystallinity small defects. Additionally, Se/S ratio is increased replacement Se Br, causing downshift Fermi levels benign band alignment shallow‐level defect. Moreover, Ba 2+ located at grain boundaries coordination S ions, passivating boundary Consequently, efficiency from 7.70 % 10.12 %. This work opens an avenue towards Sb film deposited via approach optimize its crystalline orientation defect
