Description:

In the current work, a thermoelectric device which can simultaneously harvest radiative cooling and solar heating is presented. The key component is a vertically placed transparent thermoelectric module made of thin films. By sandwiching the transparent thermoelectric module by a transparent plate at the top and a black plate at the bottom, the device is capable of harvesting radiative cooling and solar heat with the co-planar geometry in day and harvesting radiative cooling in night confirmed by outdoor and indoor measurements. Our device can be an efficient method to judiciously harvesting solar heating and radiative cooling simultaneously, paving the way for efficient energy harvesters which can be used as stand-alone power supplies for off-gird sensor modules.
