Facile Synthesis and Fabrication of poly (ortho-anthranilic acid) emeraldine salt thin film for solar cells applications


Poly (o-anthranilic acid) emeraldine salt (PANA-ES) as a conjugated semiconductor polymer has been synthesized in an acidic medium based oxidative polymerization route. The identification of the PANA-ES powder has been carried out by the following techniques: FT-IR and UV-Vis. SEM has investigated the morphology of the resulting PANA-ES powder. The structural properties of resulting nanostructured PANA-ES thin film have been investigated by X-ray diffraction (XRD). The analysis of the spectral behavior characteristics of nanostructured PANA-ES thin film, in the absorption region, displayed a direct and indirect allowed transition, and fundamental energy gaps were estimated (1.89, 3.24 eV) and (2.35, 4.06 eV), respectively. A Hybrid (polymer/inorganic) heterojunction device built on PANA-ES (deposited by spin coating technique onto p-Si single crystal wafer) was fabricated. The dark I-V characteristics were determined at different temperatures in the range from 298 to 386 K of Au/PANA-ES/p-Si/Al heterojunction diode. The device showed rectification behavior and ideality factor of 85 at ±2 V, 3.229 determined at room temperature. Under the following different light intensities: 10.1, 15.3 and 20.5 W/m2, the Au/PANA-ES/p-Si/Al showed a photovoltaic performance data with short circuit current (Isc) and open circuit voltage (Voc) of (0.09 mA 1,41 mV), (0.16 mA, 176 mV) and (0.26 mA and 211 mV) respectively. The filling factor (FF) and electrical conversion efficiency (η) of Au/n-PANA-ES/p-Si/Al device were found to be 0.205 and 6.07 %, respectively.
