Films on ITO of [N(C4H9)4]5H[P2V3W15O59{(OCH2)3CNHCO(ZnTPP)}] (ZnTPP = zinc(II)-tetraphenyl-porphyrin) were obtained by the Langmuir-Schaefer inverted transfer method.The films were characterized by UV-vis absorption spectroscopy, XPS, AFM, and electrochemistry. Inaddition, the photovoltaic performances of the Langmuir-Schaefer films were investigated by photo-current transient measurements, which show significant photocurrent response.
