Long-range exciton dissociation in layered organic solar cells

Song, Qun Liang / Yang, Hong Bin / Li, Chang Ming

Long-range charge transfer in a donor-spacer-acceptor system is observed. When tris-8-hydroxy-quinolinato aluminum (Alq3) is used as a spacer between copper phthalocyanine (CuPc, donor) and C60 (acceptor), electron transfer over 14 nm from CuPc to C60 and hole transfer over 30 nm from C60 to CuPc occur. Two charge transfer mechanisms are identified by this study: electron tunneling via gap states of Alq3 (the lowest unoccupied molecular orbitals of Alq3 act as an energy barrier) and hole transport via the highest occupied molecular orbitals of Alq3, which act as step-stone levels. A thin spacer with suitable energy levels is suggested to improve the power conversion efficiency by inhibiting the recombination of geminate pair polarons.
