Abstract
The authors investigated heterojunction organic solar cells composed of different metal phthalocyanines ( M Pcs , M = Fe , Co, Ni, Cu, and H 2 )/fullerene ( C 60 ) and compared the solar cell characteristics with the field-effect hole mobilities ( μ h ) and exciton diffusion length ( L ex ) of the different M Pcs . They observed that the short circuit current ( J SC ) is linearly dependent on the μ h of the M Pcs , except for ZnPc. They also estimated the L ex of the M Pcs by creating a line of best fit using the action spectra of the external quantum efficiency in the solar cells and found that J SC is closely correlated with the L ex of the M Pcs .Keywords
