Flower Power: Exploiting Plants' Epidermal Structures for Enhanced Light Harvesting in Thin‐Film Solar Cells

Light-harvesting micro-/nanohierarchical structures replicated from plants' epidermal cells are exploited for photovoltaic applications. Their broadband and omnidirectional antireflection properties, together with their light-trapping capability, are analyzed experimentally. Power conversion efficiency gains are reported after integrating those replicas onto optimized state-of-the-art organic solar cells. The proposed approach can be applied to different plant species and photovoltaic technologies.
