This research project aims to identify, prepare, and test solar selective absorber coatings to increase the efficiency and drive down the cost of solar thermal technologies. A solar selective coating is the active material that absorbs sunlight in a solar thermal collector. For efficient photothermal conversion of the solar spectrum a coating must maximize the solar absorption while minimizing the thermal emittance at the operational temperature of the solar collector. The requested equipment is an integrating sphere covering the infrared region for a spectrometer to measure the emittance of solar selective coatings. This equipment will compliment our existing infrastructure to measure the absorption.

该研究项目旨在确定、制备和测试太阳能选择性吸收涂层，以提高效率并降低太阳能热技术的成本。太阳能选择性涂层是太阳能集热器中吸收阳光的活性材料。为了太阳光谱的有效光热转换，涂层必须在太阳能集热器工作温度下最大化太阳能吸收，同时最小化热发射。所要求的设备是一个覆盖红外区域的积分球，用于光谱仪测量太阳能选择性涂层的发射度。该设备将补充我们现有的基础设施来测量吸收。
