The development of organic polymer semiconductor layers is addressed at the contemporary stage for optoelectronics and especially for the development of photovoltaic devices [1,2]. In this paper the synthesis of new metallophthalocyanine (Pc-Me) derivatives, including zinc, cobalt and copper hydroxyphthalocyanines, zinc tetrahydroxiphthalocyanines and other Pc-Zn derivatives is discussed. Their synthesis allowed solving one of the common difficulties in the properties of composites - low solubility in organic solvents. The obtained metallophthalocyanines demonstrated solubility in chloroform and in other solvents of tens of times greater than the solubility of Pc-Zn (Aldrich). Basing on the synthetized phthalocyanines and polyepoxipropylcarbazole compositions, thin layers with an HO-Pc-Zn content of 10 to 80 mass % have been made. These layers were deposited on a polyethylene terephthalate support coated with a thin optically transparent chromium layer. Investigation of the photosensitivity of the layers was carried out by means of a special installation by the method of plotting the potential deposited on the surface of the layer of HO-Pc-Zn- carbazolic polymer, both in full illumination and wave-length л=700 nm. The most useful properties have been demonstrated by the photosensitive layers of carbazole polymer with metallo phthalocyanine and with 2,4,7-trinitrofluorenone added. Layers that do not contain HO-Pc-Zn are sensitive only in the л=560-650 nm range, and those with metallophthalocyanine are sensitive across the visible and near infrared range л=700-800 nm. Thus, these polymeric layers with a content of 50-80 mass % of metallophthalocyanine can be used for production of some photovoltaic devices, including photovoltaic cells. |
