How high local charge carrier mobility and an energy cascade in a three-phase bulk heterojunction enable >90% quantum efficiency.

Abstract

Charge generation in champion organic solar cells is highly efficient in spite of low bulk charge-carrier mobilities and short geminate-pair lifetimes. In this work, kinetic Monte Carlo simulations are used to understand efficient charge generation in terms of experimentally measured high local charge-carrier mobilities and energy cascades due to molecular mixing.
