• openAccess   Insight into Photon Recycling in Perovskite Semiconductors from the Concept of Photon Diffusion 

      Ansari-Rad, Mehdi; Bisquert, Juan American Physical Society (2018)
      Photon recycling has been proven to be an important process in metal halide perovskite thin films. We propose a model of photon recycling based on the photon diffusion concept that can interpret experimental observations ...
    • closedAccess   Theory of Light-Modulated Emission Spectroscopy 

      Ansari-Rad, Mehdi; Bisquert, Juan American Chemical Society (2017-07)
      Perovskite solar cells and fluorescent collectors formed by a dispersion of quantum dots in a transparent solid are paradigmatic devices for photon capture and utilization that involve the coupling of photon displacement, ...
