项目摘要

This is a proposal for a joint research programme involving Swansea University (SU) and the Luxembourg Institute of Science and Technology (LIST)The development of sustainable energy is one of the key scientific challenges of the 21st century. Environmental concerns have led to an increased interest in the use of solar energy as an alternative to fossil fuel based energy sources. In the solar energy field, significant research attention is being given to the processes of collection and storage, either in the form of heat or by direct conversion to electricity. The most important part of solar collectors is the solar selective coatings, which directly affect the efficiency of the system.New nano-structured metamaterial based absorbers have many benefits over conventional absorbers, such as miniaturisation, adaptability and frequency tuning. However, there are two major challenges in producing these new metamaterial based absorbers. The first is to find the optimal nanostructure design, while the second is its synthesis within current nano-technological limits. The project address the first challenge via a new multi-scale computational framework. Advanced computational techniques will be develop to perform the simulations at the nano-scale and explore the vast design space for the nano-structure. A novel methodology to couple the nano and micro scales will be developed and implemented and an optimisation technique applied at the micro scale to find the optimal nano-structure.The second challenge will be addressed by employing the unique world prototype machine at LIST capable of fabricating/replicating nano/micro metallic structures by electrochemical deposition. The chemical stability of the materials employed at the nano-scale will also be considered with the objective to guarantee chemical stability at high temperatures, with the aim of boosting light absorption efficiency.

这是一项由斯旺西大学(SU)和卢森堡科学与技术研究所(LIST)联合开展的研究计划的提案。可持续能源的发展是21世纪的关键科学挑战之一。对环境的担忧导致人们对使用太阳能作为化石燃料能源的替代品越来越感兴趣。在太阳能领域，以热能或直接转化为电能的方式收集和储存的过程受到了极大的研究关注。太阳能集热器最重要的部分是太阳能选择涂层，它直接影响到系统的效率。新型纳米结构超材料吸热材料与传统的吸热材料相比具有许多优点，如小型化、适应性和频率可调。然而，在生产这些基于超材料的新型吸波材料方面存在两个主要挑战。第一是寻找最优的纳米结构设计，第二是在现有的纳米技术限制下进行合成。该项目通过一个新的多尺度计算框架解决了第一个挑战。将开发先进的计算技术来进行纳米级的模拟，并探索纳米结构的广阔设计空间。将开发和实施一种新的方法来耦合纳米和微米尺度，并在微观尺度上应用优化技术来寻找最佳的纳米结构。第二个挑战将通过使用列表中唯一的能够通过电化学沉积来制造/复制纳米/微米金属结构的世界原型机器来解决。还将考虑在纳米级使用的材料的化学稳定性，目的是确保高温下的化学稳定性，以提高光吸收效率。
