论文摘要
太阳（〜6000 K）和外太空（〜3 K）是人类人类的原始热源和下沉。吸收太阳辐射和收获外太空利用空间的寒冷的能源应用吸引了研究人员的极大兴趣。但是，由于固有的红外光谱冲突，将这两个功能结合在静态设备中进行连续能量收集是无法实现的。在这项研究中，我们开发了光谱光热和夜间辐射天空冷却模式的光谱自适应吸收器/发射极（SSA/E），具体取决于二氧化钒涂层层的相变。 24小时的夜晚测试表明，制造的SSA/E具有连续的能量收集能力和改善的总体能量利用性能，从而在未来的能源应用中显示出巨大的潜力。
The sun (~6000 K) and outer space (~3 K) are the original heat source and sink for human beings on Earth. The energy applications of absorbing solar irradiation and harvesting the coldness of outer space for energy utilization have attracted considerable interest from researchers. However, combining these two functions in a static device for continuous energy harvesting is unachievable due to the intrinsic infrared spectral conflict. In this study, we developed spectral self-adaptive absorber/emitter (SSA/E) for daytime photothermal and nighttime radiative sky cooling modes depending on the phase transition of the vanadium dioxide coated layer. A 24-hour day-night test showed that the fabricated SSA/E has continuous energy harvesting ability and improved overall energy utilization performance, thus showing remarkable potential in future energy applications.
