Research on organic solar cells is being actively conducted. Organic solar cells have many merit than inorganic solar cell, but are slightly difficult to commercialize because of their low conversion efficiency. Effect factor of conversion efficeinecy in organic solar cells is HOMO value, band gap, charge career mobility and so on. The lower the HOMO, the narrower the band gap, the better the charge mobility, the better the efficiency can be. DFPz can have low HOMO because it has two fluorine atoms and two nitrogen atoms that have strong withdrawing effect, and polymerization with BDTT so it can have small bandgap. Phenazine has extended benzene ring than quinoxaline units so it attribute good charge mobility to DFPZ’s smoothness and high efficiency organic solar cell can be made based on this. One of donor material is PBDTT-DoDFPZ and other PBDTT-DHDFPz and acceptor unit used PCBM. The result of PCE in PBDTT-DoDFPZ is 2.76% which is higher than PBDTT-DT-DoDFP’s power conversion efficiency of 2.73%.
