Phthalocyanine-Based Schottky-Type Photovoltaic Cells with Magnetron Sputtered Al Electrodes
This work addresses the use of a sputtering technique for fabricating the top contacts to conventional sandwich-type ITO\phthalocyanine\Al cells. Current-vs-voltage characteristics of these cells measured both in dark and under illumination are compared with those of identical cells, but hearing a thermally evaporated Al cathode. The greatly improved efficiency is revealed in the former case: in particular, the fill factor increased by a factor of three.
