Description of exciton transport in a TiO2/MEH-PPV heterojunction photovoltaic material

Abstract:

A model for exciton transport in conjugated polymers has been developed taking into account inhomogeneous broadening of exciton energy level. Time-resolved photoluminescence data were used to determine the parameters of the model, such as exciton lifetime, effective number of exciton energy levels within inhomogeneously broadened density of states, hopping distance and hopping rate constants for excitons. Using the developed model a non-monoexponential decay of photoluminescence of the conjug...
