Description
Summary:We present the results of comparative investigations of the effect of a direct solvent-free modification of ... thin films with photosensitive molecules: aminosubstituted polycyclic aromatic hydrocarbons (1-aminopyrene, 1-pyrenemethylamine hydrochloride, 1,5-diaminonaphthalene) and meso-tetraphenylporphine on their optical properties, photoluminescence, and photoelectric characteristics of Au/.../Si photodiode structures (... = 400-1100 nm). The optical properties (n, k) of the investigated C60 films are shown to differ slightly. The photoluminescence spectra measured at 2 K demonstrate a redistribution of the constituent bands intensities and their overall reduction for all C60 modifications. The greatest enhancement of the photocurrent and the photoconversion efficiency is observed for structures with C60 layers modified with meso-tetraphenylporphine.
