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.

Beam-controlled spectral-selective architecture for a radiative cooler

A solar vapor generator system and method are provided. In some embodiments, the system has near perfect energy conversion efficiency in the process of solar vapor generation below room temperature. Remarkably, when the operation temperature of the system is below that of the surroundings, the total vapor generation will be higher than the upper limit that can be produced by the input solar energy.

System and method for solar vapor evaporation and condensation

Disclosed herein are systems and methods for passively cooling water vapor to enable efficient condensation, and methods of making such systems. A passive cooler can include a thermally conductive substrate having a first side and a second side opposite the first side, a coating disposed on at least a portion of the first side of the substrate, and a housing having one or more insulative walls. The insulative walls may define a vapor flow channel from an inlet to an outlet of the housing such that the second side of the substrate is exposed to water vapor flowing through the vapor flow channel.
