摘要

Solar spectrum absorbing and harvesting are important for the utilization of solar energy. In this paper, we propose a metamaterial-based frustum of cones array solar energy absorber which appears an average absorptivity of 0.98 in the entire spectrum (i.e., 0.2-2.5 μm) with independent of the incoming light polarization state as well as the wide incident angle of as large as 50°. The efficient light harvesting property can be explained as the syner-gistic effect of the slow light mode, localized surface plasmon resonant effect and absorption induced by inter-band transition.
