ABSTRACT Recently, nonreciprocal structures that violate Kirchhoff’s law of thermal radiation have attracted considerable interest for their potential in solar energy harvesting applications. However, previous research has primarily focused on mid-infrared wavelengths rather than on the main solar wavelength range where sunlight intensity is concentrated. In this work, we theoretically demonstrate a nonreciprocal structure operating within the main solar spectrum, specifically tailored to meet the requirements of solar cell applications.
