摘要

Harvesting incident photons is the first step in a photo-induced process such as photocatalysis, photovoltaics or photodetection, which crucially governs the process performance.Unfortunately, extensive energy losses are observed in this step due to severe surface reflections and limited optical paths of the shortwavelength light [1].Thus, it is desirable to develop an advanced nano/macro structure that could efficiently harvest light of different wavelengths and minimize excessive photo-reflection and photo-heating [2,3].
