Paper Abstract

Exciton transport plays an important role in the overall exciton dissociation process and must be optimized to yield high efficient OPV device. In this contribution, the influence of solvents and the nanoscale phase separations they caused on the glass transition temperatures (Tg) of P3HT-PCBM mixture were studied by reverse mapping mesoscale simulation results back to the molecular dynamics. Glass transition temperatures of P3HT-PCBM without solvent and with chloroform, dichlorobenzene, and chlorobenzene were obtained. Diffusion and reorientation ability of molecules and their subgroups at the temperature near Tg were also discussed.
