The authors investigated heterojunction organic solar cells composed of different metal phthalocyanines (MPcs, M=Fe, Co, Ni, Cu, and H2) /fullerene (C60) and compared the solar cell characteristics with the field-effect hole mobilities (μh) and exciton diffusion length (Lex) of the different MPcs. They observed that the short circuit current (JSC) is linearly dependent on the μh of the MPcs, except for ZnPc. They also estimated the Lex of the MPcs by creating a line of best fit using the action spectra of the external quantum efficiency in the solar cells and found that JSC is closely correlated with the Lex of the MPcs.
