摘要：Passive radiative cooling technology has attracted extensive attention as it addresses the potential applications in effectively cooling photovoltaics and related systems. Here, we performed comprehensive multidimensionaland multiphysical opto-electro-thermal (OET) modeling, which was used to design asilicon-based radiative cooling system for a solar cell (SC). Our study simultaneously takes into accountthe coupled effects of the radiative cooling characteristics, carrier thermodynamics, and electrodynamicbehaviors of SCs in the spatial and frequency domains. Based on a comprehensive photonic design, wepresented a radiative cooler with near-ideal spectral selectivity from the sunlight to the infrared band. Thefundamental OET physical mechanisms and the effect of temperature on the performance of SCs wereexplored. A comparable study on the performance parameters of the SCs with and without a radiativecooler was formulated, which revealed that the SC temperature can be reduced by over 10 °C and theabsolute power conversion efficiency (PCE) can be increased by 0.45% after employing a photonicradiative cooler. Our OET study provides a ready method to explore the comprehensive OET physics inphotovoltaic systems.
