Scopus Investigation of photodetector and photovoltaic properties of H2Pc/CuO and H2Pc/ITO junctions produced with modified H2Pc(Springer Nature, 2024) Unal, F.; Aktas, S.; Kurt, M.S.; Koc, M.M.; Arslan, T.; Coskun, B.; Gur, M.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.

Therefore, further modifications are needed for the use of such substances. In this study, polymer particles (GD) that were economical and directly effective against anionic pollutants were synthesized as an alternative. GD particles were synthesized with glutaraldehyde and diethylenetriamine as monomers for the first time. The polymer particles were characterized in detail. Then, GD particles were used in the adsorption of anionic Bromophenol blue (BPB) and phenol (PH). As a result, it was determined that i) the adsorption process between GD particles, Bromophenol blue and phenol was chemisorption, ii) the adsorption of BPB and PH on to GD particles obeyed the Langmuir isotherm and pseudo second order kinetic model. pH, temperature, initial dye concentration, adsorbent dosage, and contact time were determined orderly 4, 50 °C, 300 mg L−1, 10 mg, and 180 mins for BPB and 5, 50 °C, 10 mg L−1, 15 mg, and 30 mins for PH. The maximum adsorption capacities of GD polymer particles for BPB and PH were ascertained as 136.40 mg g−1 and 98.26 mg g−1, respectively. As a result, it was produced economical, simple, feasible, and functional adsorbents against anionic pollutants.
