Tanjaya, Takao Mori, Mater. Today 75, 20-26 (2024)Abstract A thermoelectric device which can simultaneously harvest radiative cooling and solar heating is presented. 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., , ,  , , ,  Thermoelectric generation (TEG) by radiative cooling to the sky⇔ Sunlight reflection by daytime radiative coolerHarvesting radiative cooling & solar heating in day for TEG⇔ Solar absorbers and radiative coolers are non-coplanarSolar absorbers and radiative coolers are coplanar⇒ Improving TEG per unit areaTransparent thermoelectric materials allow coplanar design⇒ IGZO as n-type, CuI as p-type TE thin filmsIGZO and CuI fabricated on each side of the glass substrate are transparentBlackbody paint: absorptive in VIS-NIR & MIRPET sheet: transparent in VIS-NIR, absorptive in MIRSimultaneously harvesting radiative cooling and solar heating  for TEG with the coplanar structure confirmed by indoor and outdoor measurements 1.
