Therefore, careful material selection for the anode and cathode is essential to enhance reactant/product transport and optimize water management under ‘dry cathode’ conditions. This study investigates the wetting characteristics of two commercially available porous transport layers (PTLs) used in AEM-WE: carbon paper and carbon paper with a microporous layer (MPL). Wettability was measured under static, quasi-static, and dynamic conditions to assess the effect of water and electrolytes (NaOH, KOH, K<sub>2</sub>CO<sub>3</sub>) across concentrations (up to 1 M) and operational temperatures (20 °C to 92 °C). Carbon paper exhibits mild hydrophobicity (advancing contact angles of <span>(:sim)</span>120°, however with receding contact angle <span>(:sim)</span>0°), whereas carbon paper with MPL demonstrates superhydrophobicity (advancing and receding contact angles &gt;145° and low contact angle hysteresis), maintaining a stable Cassie-Baxter wetting state. Dynamic wetting experiments confirmed the robustness of the superhydrophobicity in carbon paper with MPL, facilitating phase separation between hydrogen gas and liquid water. The presence of supporting electrolytes did not significantly affect wettability, and the materials retained hydrophobic properties across different temperatures. These findings highlight the importance of MPLs in optimizing water transport and gas rejection within AEM-WEs, ensuring efficient and stable operation under “dry cathode” conditions. These PTLs (with and without the addition of the MPL) were integrated into AEM-WE and polarization curves were run. Preliminary data, in a specific condition, suggested the presence of the MPL within the PTL enhance AEM-WE performance.</p></div>","PeriodicalId":692,"journal":{"name":"Materials for Renewable and Sustainable Energy","volume":"14 2","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40243-025-00324-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are limited studies on using pulsed laser-synthesized colloidal silver nanoparticles as modified photoanodes within the DSSC architecture. In this study, colloids of silver nanoparticles (Ag NPs) with varying concentrations are produced using the advanced nanosecond pulsed laser ablation in liquid technique and subsequently implanted into the TiO<sub>2</sub> photoanode of the N719 DSSC, forming an Ag@TiO<sub>2</sub> nanostructure. The optical properties, investigated through UV-visible spectroscopy, reveal a concentration-dependent absorbance of colloidal Ag NPs based on the duration of laser exposure. Using a second harmonic wavelength of 532 nm leads to the formation of spherical and quasi-spherical nanoparticles with a size range of 20–180 nm. The photovoltaic performance of a solution-processed DSSC with the Ag@TiO<sub>2</sub> modified photoanode at varying concentrations of Ag NPs is studied, with an optimal concentration of 13 µg/ml and doping (wt%) of 2.0%, resulting in almost a two-fold increase in photocurrent density (<i>J</i><sub><i>sc</i></sub>) of 13.56 mA/cm<sup>2</sup>, and maximum power output <i>(P</i><sub><i>max</i></sub><i>)</i> of 1.125 mW, with the highest power conversion efficiency (PCE) of 4.50% when compared with standard DSSC. The DSSC characterizations, including transient photocurrent response, showed higher current density for Ag-doped photoanodes compared with bare TiO<sub>2,</sub> and the electrochemical impedance of the modified DSSC showed the lowest transfer resistance (R<sub>c-t</sub>) of 3.6 Ω. Finally, the developed plasmonic DSSC highlights the effect of enhanced light absorption through localized surface plasmon resonance (LSPR) and enhanced charge transfer within the absorber layer, resulting in improved solar cell performance.</p></div>","PeriodicalId":692,"journal":{"name":"Materials for Renewable and Sustainable Energy","volume":"14 2","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40243-025-00315-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145143685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
