These donor-acceptor small molecules incorporate nitro or fluorine substituents into the NBD core to enhance non-fullerene organic solar cells (NF-OSCs) performance. The electron-withdrawing nature of these groups reduces frontier orbital energy levels, improving electronic properties critical for device efficiency. Intermolecular energies, including electrostatic and Lennard-Jones interactions, were calculated for Ai/acetonitrile mixtures, providing insight into interaction potentials. DFT and TD-DFT analyses revealed the molecules’ geometric structure, optoelectronic features, optical behavior, and charge transport properties of the designed molecules. These compounds exhibit narrower band gaps ranging from 2.25 to 1.67 eV, along with high absorption maximum (λ_max between 463 and 472 nm). Furthermore, the lower binding energies (E_b = 0.48–0.55 eV), indicate enhanced exciton dissociation efficiency, driven by significant charge transfer from donor to acceptor, as confirmed by FMOs, PDOS, MEP, and TDM analyses. The designed molecules exhibit remarkable photovoltaic performance, including higher open-circuit voltages (V_oc) and large fill factors (FF). Among these, A₄ emerges as the most promising candidate due to its reduced optical bandgap, maximum absorption wavelength, and superior electronic and photovoltaic properties. Blending A₄ with an NBD-based donor highlights efficient charge transfer dynamics, reinforcing its strong potential for practical applications in OSCs. This work highlights the potential of NBD-based NFAs in advancing NF-OSC technology, providing a platform for designing efficient, high-performance photovoltaic materials.</div></div>","PeriodicalId":22245,"journal":{"name":"Synthetic Metals","volume":"311 ","pages":"Article 117846"},"PeriodicalIF":4.0,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143173551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From this standpoint, gamma irradiation treatment provides a viable approach to enhance the performance of low-cost, platinum-free counter-electrodes (CEs) by increasing the number of active sites, thereby improving their catalytic efficiency in DSSCs. To the best of our knowledge, for the first time, innovative Chitosan@polyvinyl alcohol@Titanium dioxide (Chitosan@PVA@TiO₂) (CPT) hybrid films were developed as a catalytic CE substance and were subjected to a range of in-situ gamma irradiation doses (0, 10, 20, 30 and 40 KGy) with the goal to further improving their microstructural and physicochemical qualities. Coupled with a J–V variable evaluation, physical assessments of the microstructure, porosity, morphology, contact angle, optical, and electrochemical impedance spectroscopy (EIS) properties of CEs were carried out. The surface properties of the treated composites improved progressively with increasing gamma doses, reaching optimal levels at 30 KGy (i.e., apparent porosity = 72.5 %, average roughness (Ra) = 5.31 µm) compared to the pristine CE material. Prolonged gamma irradiation enhanced DSSC efficiency, achieving 6.45 % at 10 KGy and 7.14 % at 20 KGy. The high-energy gamma photons facilitated charge carrier movement within the CPT compounds while reducing recombination by creating conditions favorable for charge dissociation. Hence, improved mobility and reduced resistive limitations equate to longer lifespans and more efficient charge transfer within the solar cell. In this regard, the CPT catalytic CE's optimized yield of 8.57 % and short-circuit photocurrent density (J_sc) of 19.1 mA/cm² were achieved after 30 KGy of modification of the surface. Compared to the pristine sample, effectiveness increased by 41.2 %. This enhancement in photovoltaic performance was attributed to the introduction of oxygen-enriched free radicals into the CPT structure, which created continuous channels for rapid electron transfer. Considering all aspects, this work highlights the critical role of gamma-irradiated CPT catalytic CEs in enhancing DSSC performance, offering a new approach to improving the efficiency of these devices.</div></div>","PeriodicalId":22245,"journal":{"name":"Synthetic Metals","volume":"311 ","pages":"Article 117841"},"PeriodicalIF":4.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143173621","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
