Donor-acceptor-donor (D-A-D) type polycyclic aromatic hydrocarbon and its derivatives have been widely used in the design of photovoltaic materials and have made great breakthrough in recent years, due to their advantages of unique large planar structure, high charge mobility, excellent light absorption performance, thermal and light stability. The latest research progress of small-molecule photovoltaic materials based on D-A-D type polycyclic aromatic hydrocarbons is reviewed. The relationships between photovoltaic properties and the molecular structures are analyzed systematically.
Key words: polycyclic aromatic hydrocarbon, solar cell, small-molecule, organic photovoltaic material
