Abstract:

Phthalocyanine is used in many scientific and industrial fields such as nonlinear optical devices, electrophotographic applications, photodynamic therapy applications, infrared applications, sensor applications and catalyst applications. The applications of the phthalocyanine molecule in hetero-compound structures have been studied before. The obtained results revealed that phthalocyanine can be used in photodetector and photodiode applications. Organic detectors can be applied to flexible surfaces and their production costs are lower than metal-based photodetectors. Considering these features of organic detectors, phthalocyanine-based organic photodiodes were produced by using copper-phthalocyanine salts in our project. The optoelectronic properties of the produced Al/p-Si/CuPc/Al photodiodes were investigated, and their I – V, I – t, and photoresponsivity behaviours were evaluated. Since I-V measurements show that the current changes with the increase of illumination intensities, our study shows that Al/p-Si/CuPc/Al structures have photodiode properties.
