  • Patent number: 11844228
    Abstract: A leaf inspired biomimetic light trapping scheme for ultrathin flexible graphene silicon Schottky junction solar cell. An all-dielectric approach comprising of lossless silica and titania nanoparticles is used for mimicking the two essential light trapping mechanisms of a leaf: (1) focusing and waveguiding and (2) scattering. The light trapping scheme uses two optically tuned layers and does not require any nano-structuring of the active silicon substrate, thereby ensuring that the optical gain is not offset due to recombination losses.
