Consistent formulation of the crossover from density to velocity dependent recombination in organic solar cells
Ansari-Rad, Mehdi; Garcia-Belmonte, Germà; Bisquert, Juan AIP Publishing (2015)Carrier recombination is a central process in bulk heterojunction organic solar cells. Based on the competition of hopping rates that either implies escape in a broad density of states or recombination across the interface, ... -
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 ... -
Interpretation of Diffusion and Recombination in Nanostructured and Energy-Disordered Materials by Stochastic Quasiequilibrium Simulation
Ansari-Rad, Mehdi; Anta, Juan A.; Bisquert, Juan American Chemical Society (2013)The main electronic feature of many nanocrystalline semiconductors and I organic materials is the presence of a distribution of localized states in the system with a broad energy dispersion. Carrier transport and recombination ... -
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, ...
