Abstract: A passive cooler of the disclosure includes a thermal emitter having a substrate and a coating disposed on at least a portion of a first side of the substrate. The cooler has a beam guide made from a material having a high absorption to solar wavelengths and high reflectance at mid-infrared wavelengths. The beam guide is configured such that at least a portion of incident light is acted on by the beam guide before reaching the thermal emitter. In some embodiments, the beam guide has a graded optical index.

Abstract: A solar vapor generation system includes a substrate configured to wick solution from a reservoir. The substrate includes a first planar sheet having a first end, and a second planar sheet having a first end. The first end of the first planar sheet is connected to the first end of the second planar sheet at an angle of less than 180.0 degrees. In some embodiments, the angle is less than 90.0 degrees. At least a portion of the first planar sheet is configured to be in contact with the solution. The system includes a support, configured to support the substrate at a position near a surface of the solution.
