| dc.description.abstract | The photoelectrochemical properties of a solid-state and a quasi-solid state photoelectrochemical cell (PEC) based on a polymer PDTSTTz and a blend of PDTSTTz:PCBM with an amorphous polymer electrolyte Poly[oxomethylene-olig(oxyethylene )] and ionic liquid complexed with redox couple iodide/triiodide, and oxidized PEDOT as counter electrode were studied. PEDOT:PSS were spin coated to the substrate and the photo-response of the fabricated device were studied and the followings results were obtained: open-circuit voltage of 311 mV and a short-circuit current of 45.4 μAcm-2 and fill factor (FF) 0.34 for the device PEDOT:PSS/PDTSTTz:PCBM/POMOE:I-3/I- at light intensity of 100 mWcm-2. For all devices the photocurrent action spectra of the front and back side were studied and compared. During illumination, a cathodic photocurrent was observed, indicating that the neutral polymer PDTSTTz behaves as a p-type semiconductor. IPCE% ranges from 0.019% to 0.6% from the front side illumination (ITO/PEDOT) were obtained from the different types of device, in addition the Uv-vis absorption spectra of the PDTSTTz film was compared with the photoresponse of the different device and the results were consistent. | en_US |
