太阳能选择性吸收器是太阳能热水器、聚光太阳能发电、太阳能热电发电、太阳能热光伏等太阳能热技术的核心部件。彩色太阳能选择性吸收剂可以提供超越能源性能的新的自由和灵活性，这将导致太阳能技术的更广泛应用。在这项工作中，我们提出了一种基于Cu/TiNxOy/TiO2/Si3N4/SiO2多层结构的单一衬底上不同颜色的彩色太阳能吸收器阵列的单片集成。利用组合沉积技术，通过改变SiO2层厚度，实验证明了具有16个颜色单元的彩色太阳能吸收体阵列。各颜色单元的太阳吸收率和热发射率分别高于92%和低于5.5%。彩色太阳能选择性吸收阵列在保持高能量性能的同时，具有丰富多彩的外观和可设计的图案。它是许多太阳能应用的新候选，特别是在建筑集成和军事伪装方面。(C) 2015美国光学学会
Solar selective absorbers are the core part for solar thermal technologies such as solar water heaters, concentrated solar power, solar thermoelectric generators and solar thermophotovoltaics. Colorful solar selective absorber can provide new freedom and flexibility beyond energy performance, which will lead to wider utilization of solar technologies. In this work, we present a monolithic integration of colored solar absorber array with different colors on a single substrate based on a multilayered structure of Cu/TiNxOy/TiO2/Si3N4/SiO2. A colored solar absorber array with 16 color units is demonstrated experimentally by using combinatorial deposition technique via changing the thickness of SiO2 layer. The solar absorptivity and thermal emissivity of all the color units is higher than 92% and lower than 5.5%, respectively. The colored solar selective absorber array can have colorful appearance and designable patterns while keeping high energy performance at the same time. It is a new candidate for a number of solar applications, especially for architecture integration and military camouflage. (C) 2015 Optical Society of America
