  author={Zachary J. Berquist and Andrew J. Gayle and Neil P. Dasgupta and Andrej Lenert},
Although spectrally selective materials play a key role in existing and emerging solar thermal technologies, temperature-related degradation currently limits their use to below 700C in vacuum, and even lower temperatures in air. Here we demonstrate a solar-transparent refractory aerogel that offers stable performance up to 800C in air, which is significantly greater than its state-of-the-art silica counterpart. We attribute this improved stability to the formation of a refractory aluminum…
