Non-Fullerene-Derivative-Dependent Dielectric Properties in High-Performance Ternary Organic Solar Cells

Ternary blend solar cell, a promising strategy by introducing additional component with either an extra acceptor or an extra donor to a conventional binary blend, improves the performance of the solar cell. However, the mismatch of energy band structure and the tradeoff between open-circuit voltage (Voc) and short-circuit current density (J9c) can be heavily affected by incorporating an inappropri...
