Investigation of photodetector and photovoltaic properties of H2Pc/CuO and H2Pc/ITO junctions produced with modified H2Pc

Abstract

In this work, it was aimed to provide an alternative to organic-based photodiode detectors (OPDs), solar cell with the modified H2Pc organic thin film heterojunctions. For this purpose, the modified H2Pc organic thin film was grown on ITO/glass and CuOx/ITO/glass substrates via thermal evaporation method and their optoelectronic properties were compared with each other and other organic-based devices. The crucial optical parameters of the fabricated heterojunctions were determined in the wavelengths range of 300–800 nm. In order to perform electrical characterisation, Ag metal contacts were grown on the heterojunctions and Ag/H2Pc/ITO/Ag and Ag/H2Pc/CuOx/Ag devices were fabricated. Diode, photovoltaic and photodetector parameters of the fabricated devices were investigated in the applied potential of ± 3 V under dark and several light intensities. Ultimately, it can be stated that the fabricated devices may offer an alternative to OPDs and organic-based solar cell.Please check and confirm the author names and initials are correct.
