Abstract. We present measured optical absorptivity, emissivity, and maximum solar-heated temperatures for micropatterned molybdenum. The molybdenum samples were fabricated using laser micromachining and characterized using an integrating sphere and an infrared microscope. In-air solar simulator-heated temperature results for the molybdenum samples with different microstructures are presented, and COMSOL modeling is then used to predict in-vacuum maximum temperatures. A vacuum chamber was developed to reduce the convection heat loss with a mount designed to minimize conduction loss, and a maximum measured temperature of 413°C was obtained.

微图案高温选择性表面的太阳热特性

摘要。我们提供了微图案钼的测量光吸收率、发射率和最大太阳能加热温度。钼样品是使用激光微加工制造的，并使用积分球和红外显微镜进行表征。展示了具有不同微观结构的钼样品的空气中太阳能模拟器加热温度结果，然后使用 COMSOL 建模来预测真空中的最高温度。开发了真空室以减少对流热损失，其安装座旨在最大限度地减少传导损失，并获得了 413°C 的最高测量温度。
