Paper Abstract

Fluorophthlocyanine thin films were used as n-type semiconductor in organic solar cell. Heterojunction solar cells of cupper hexadecafluorophthalocyanine (F16CuPc) / copper phthalocyanine (CuPc) and F16CuPc / zinc phthalocyanine (ZnPc) deposited with PEDOT-PSS on ITO as electrode were fabricated and characterized. Comparison between CuPc and ZnPc as p-type semiconductor on photovoltaic performance was studied. Light-induced charge separation and charge transfer was investigated by current density and optical absorption. Internal microstructure in active layer was measured by transmission electron microscopy, X-ray and electron diffractions. The F16CuPc thin film in the deposited active layer worked for electron-accepting layer as n-type semiconductor. The photovoltaic performance was original in charge transfer from CuPc to F16CuPc in active layer.
