Abstract: A solar-energy module is disclosed. The module includes a first electrode configured to receive incident visible light with a different refractive index than the medium through which light travels prior to becoming incident on the first electrode, the first electrode having a first metasurface arrangement formed through the first electrode, and configured to selectively i) match the optical impedances of the first electrode and the medium, and ii) cause light to be refracted substantially away from normal refraction angle, a photon-absorbing material coupled to the first electrode on a first surface of the photon-absorbing material and configured to receive refracted light through the first electrode and adapted to produce an electrical current in response to the refracted light, length of the photon absorbing material substantially larger than thickness of the photon-absorbing material, and a second electrode coupled to the photon-absorbing material on a second surface of the photon-absorbing material.
