Abstract

Singlet fission in organic semiconductors is a promising concept that can be used to increase the efficiency of solar photovoltaic cells. Upon light absorption a singlet exciton (S = 0) is created, which splits into two triplet excitons (S = 1), via an intermediate triplet-pair state (S = 1 ⊗ S = 1). This carrier-multiplication process potentially reduces the thermalization losses...
