We examined the interaction among different types of cool materials, starting with a base coating comprising highly reflective paint (HR), further enhanced with thermochromic (TH) and photoluminescent pigments (PH). These materials were applied onto a PVC substrate and subsequently overlaid with a retroreflective (RR) layer containing fine-grained (FG) and medium-grained (MG) glass microspheres at varying weight percentages (25, 40, and 50 wt%). A combination of optical and thermal analysis techniques was used to assess the interactions between the layered materials and the impact of RR coatings on key performance metrics. Results highlight the significant influence of glass microsphere size: MG microspheres achieved total solar reflectance values exceeding 70 %, while FTIR analysis showed stable thermal emittance around 50 %, with a notable 20 % reduction in the 11–19 μm range for MG samples. Surface roughness measurements further revealed smoother surfaces in MG-coated samples compared to FG ones. Decay time simulations under low and high irradiance conditions for PH samples indicated prolonged photoluminescent persistence in FG-based systems, especially under low irradiation. Overall, while MG microspheres offer superior solar reflectance, FG microspheres demonstrated more balanced performance, making them particularly promising for UHI mitigation strategies in urban coatings.</div></div>","PeriodicalId":429,"journal":{"name":"Solar Energy Materials and Solar Cells","volume":"289 ","pages":"Article 113659"},"PeriodicalIF":6.3,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143911454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, studies have revealed that ECDs suffer from the adsorption of the BMIMBF<sub>4</sub>'s cations on the electrode surface, causing increased charge transfer resistance, thus leading to poor electrochemical surface reaction and optical properties.

A critical factor in enhancing energy flux in these devices is the introduction of microscale (thermionics) or nanoscale (thermophotovoltaics) gaps between the hot thermal emitter and the cooler receiver. In thermionic converters, microscale gaps mitigate space charge effects that create energy barriers to electron flow.
