To date, two principal routes of investigation have been pursued. The initial approach involves the synthesis of the electrochromic material with the desired color, employing chemical engineering to achieve the targeted color. The second approach involves utilizing the electrochromic material as a shutter, alternating between achromatic and black states, with the device color corresponding to that of the electrolyte when the polymer is in its achromatic states. In this study, we propose a novel approach that combines the two aforementioned technologies. This novel approach offers straightforward access to bi- and trichromatic devices. The electrochromic material utilized in this study is a conjugated polymer, poly (vinyltriphenylamine) (PVTPA), which exhibits three distinct colorimetric states depending on the applied potential: achromatic, ochre, and black. This study reports the synthesis of the monomer and the polymer, as well as the electro-optical characteristics of PVTPA. The easy integration of PVTPA into devices is demonstrated by the development of bi- and trichromatic displays using different colored membranes (white, turquoise, and orange). Additionally, the switching times and color coordinates of these displays are assessed. The combination of an easily accessible electrochromic polymer and the use of colored membranes provides easy access to trichromatic devices with multiple color options.</div></div>","PeriodicalId":429,"journal":{"name":"Solar Energy Materials and Solar Cells","volume":"290 ","pages":"Article 113721"},"PeriodicalIF":6.3,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071589","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}

In this study, a cost-effective and scalable solution was developed using chemically oxidised stainless steel 304 (SS 304) sheets as the absorber material for flat plate collectors. The chemically treated SS 304 surfaces exhibited a nanoporous oxide morphology, which significantly enhanced light trapping and solar radiation absorption.

To ensure practical applicability, the chemical oxidation process was scaled up to coat 2-m-long SS 304 sheets, which were used to build a 1 × 2-m flat plate collector integrated into a thermosiphon-based solar water heater. Repeatable field tests showed an average thermal efficiency of 37.3 %, with low uncertainty less than 2 %.

Three configurations of the wire mesh placement were examined (at the base, in the middle, and submerged under the water surface) to determine the optimal position for maximizing daily water production. The proposed wire mesh functions as both a heat storage medium and a secondary porous absorber, increasing the surface area and enhancing the absorption, transmission, and storage of heat energy, thereby improving the overall productivity.

The different crucible parameters and properties were measured before and after heat treatment of 6, 12 and 18 h at 1500°C. Crucibles were characterized by: viscosity measurements at 1500 °C, micro-computed tomography, IR-microscopy, ICP-MS and optical microscopy. Experimental investigations were complemented by modelling to predict the bubble evolution during heat treatment. The bubble evolution was found to be strongly dependent on OH-group content, viscosity, impurity content and cristobalite formation kinetics, where the OH-dissolution within the crucible during heat treatment was found to be the main contributor to bubble's growth. Cristobalite formation was found to be affected by OH-group content and metallic impurity content, especially barium. In all the samples, irrespective of their sand treatment, the dominating mechanism of bubble evolution during the first hours of heat treatment was the nucleation of new bubbles. In the subsequent hours of heat treatment, the dominating mechanisms were bubble growth and their coalescence. Overall, the optimal combination of different process parameters was found for the chlorinated crucible, which exhibited highest viscosity, lower initial OH-groups content, slower bubble growth and enhanced cristobalite formation at the surface, which would all contribute to a better stability and extended crucible lifetime during the Czochralski process.</div></div>","PeriodicalId":429,"journal":{"name":"Solar Energy Materials and Solar Cells","volume":"290 ","pages":"Article 113707"},"PeriodicalIF":6.3,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071685","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}
