Abstract
Recent advances demonstrate the efficacy of ternary strategy in organic solar cells. Such excitement is achieved by synergistic improvement in both charge dynamics and energetics. The third component serves as a bridging unit to systematically optimize the charge migration, exciton lifetime, recombination, and nanomorphology. Primarily focusing on the tactics for addressing energy transfer, charge transfer, and voltage losses, specific relationship between kinetics and energetics evolution has been thoroughly analyzed upon addition of the third component. We propose that the future design should be beyond simply complementing absorption, but rather focus on how the guest molecular could specifically address the charge and energy profile. With fine control of morphology, the maximum potential of ternary blends can be realized toward highly efficient organic solar cells.
