    Garin Escriva, Moises; Fenollosa Esteve, Roberto; Alcubilla González, Ramón; Shi, Lei; Marsal Garvi, Luis Francisco; Meseguer Rico, Francisco Javier (2014-03-10)
    Article
    Open Access
    Silicon is the material of choice for visible light photodetection and solar cell fabrication. However, due to the intrinsic band gap properties of silicon, most infrared photons are energetically useless. Here, we show ...

    Photovoltaic cells on silicon spherical microcavities trap IR light, increasing the probability of photon absorption and enhancing the efficiency of solar energy devices.
  • Silicon nanocavities: Optical properties and applications 

    Fenollosa Esteve, Roberto; Shi, Lei; Rodriguez, Isabelle; Garin Escriva, Moises; Meseguer Rico, Francisco Javier (2014)
    Conference report
    Open Access
    Silicon is the key enabling material for advanced technologies in electronics, and photonics. Recently, we have developed silicon nanocavities (SNs) [1,2] with particle size between 300 nm and 3000 nm. Silicon has an ...
