We illustrate rate theories for charge transfer and separation in organic molecules for solar cells.Starting from the Fermis golden rule for weak electronic coupling,we display our developed several methods1 which cover from Marcus theory to Kramers theory.The proposed wavepacket diffusion method2,3 is also introduced to unify the coherent and hopping models for carrier motions.We further discuss the electronic structure theory for the calculations of the driving force,electronic coupling and reorganization energy that are the key parameters for charge transfer,and show several applications4,5,6.
