Harvesting sustainable energy from the sun and cold space to uninterruptedly generate green electricity provides a potential alternative way to solve the unfolding energy crisis and environmental issues. This emerging energy technology is seeing important progress and further advances remain challenging. Herein, the underlying principle, thermodynamic limit, and global potential of this technology are comprehensively reviewed. The recent advances of energy harvesters (solar absorbers or/and radiative coolers) integrated with energy converters (thermoelectric generators) are summarized, and strategies including thermal/optical/radiative cooling concentration, thermal dissipation, and geometric optimization are discussed. Last, the great prospects for uninterrupted energy harvest and electricity generation in extensive fields are outlined, and the scientific and engineering challenges for upcoming growth are proposed.

“…Several analytical studies were conducted to model and investigate the performance of RC-TEG. For example, Liu et al have modelled the RC-TEG device numerically and investigated the effects of different RC spectra and other relevant parameters on the RC-TEG device [26]. A mathematical modelling study of RC versus thermoelectric refrigerators was carried out by Liao et al [27].…”

The market for Internet-of-Things (IoT) with integrated wireless sensor networks (WSN) is expanding at a rate never seen before. The thriving of IoT also brings an unprecedented demand for sustainable micro-Watt-scale power supplies. Radiative cooling (RC) can provide a continuous temperature difference which can be converted by a thermoelectric generator (TEG) into electrical power. This novel combination of radiative cooling with TEG expands the category of sustainable energy sources for energy harvesting. However, the further application of RC-TEG requires a holistic investigation of its RC-TEG performance which is dependent on many different parameters. Using 3D finite element method simulation, this works provides a comprehensive analysis of the concept of RC-TEG by investigating the impact of radiative cooler properties, TEG parameters, and environmental conditions, to provide a full picture of the performance of RC-TEG devices. The capability of RC-TEG to provide continuous power supply is tested using real-time environmental data from both Singapore and London on two different days of the year, demonstrating continuous power supply sufficient for a wide range of physical devices.

“…For daytime radiative cooling, it is well established that the simultaneous realization of high solar reflectivity and high midinfrared emissivity is the prerequisite for high-performance daytime cooling (Figure 2a). [61][62][63] The early reports mainly employed the bilayer structure with metal mirror and emission layer to achieve radiative cooling under strong solar radiation. [10,30] Silver coating is recognized as the commonly used metal mirror for radiative coolers.…”

CO 2 in 2050. [5] Due to the second law of thermodynamics, cooling is generally more challenging than heating. Conventional vapor-compression cooling not only results in excessive energy consumption, accelerating the depletion of fossil fuels, but also degrades the atmospheric ozone, leading to notorious environmental issues. Therefore, developing novel and pollutionfree cooling technology has become an urgent demand in the following decades.Radiative sky cooling (RSC) can harvest the coldness of the universe via the 8-13 µm atmospheric window without any pollution and energy consumption, which has witnessed great progress in the last few years. [6][7][8] Since the first demonstration of daytime radiative cooling via multilayer photonic structure by Fan and co-workers in 2014, this facile cooling technology has drawn worldwide attention. [9,10] With the joint efforts, RSC technology has achieved striking advances in building cooling, [4,11] photovoltaic cooling, [12][13][14] cryogenic cooling, [15,16] RSC driving thermoelectricity, [17][18][19] atmospheric water harvesting, [20,21] personal thermal management [3,22,23] and wearable devices. [24][25][26] For building cooling, the pioneering reports by Goldstein et al. and Zhao et al. have demonstrated that building-integrated RSC modules can provide continuous day-and-night cooling and can potentially save 32%-45% of the electricity consumption for cooling in summer. [4,11] For photovoltaic cooling, selective photonic cooler can lower the temperature of solar panels by over 5.7 K and afford the greater cooling
