Abstract(in English) | Schottoky diode based on the polyalkylthiophene (PAT) film/Al has been fabricated and the current-voltage, photovoltaic effects, photocurrent excitation spectra as the function of alkylchain lengh, regioregularity, illumination side and film thickness have been measured. The diodes show excellent rectification and photovoltaic effect. The excitation spectra of photocurrent are similar to that of absorption and the larger photocurrent has been obtained, when the diode is illuminated to Al side. The magnitude of photocurrent decreased with increasing the alkylchain length and the regiorandumness. The results indicate that the photocarriers are generated in the depletion layer at the Schottky junction of PAT/Al. Excitons generated in a sigle molecule at the depletion layer dissociate into photocarriers with a help of built-in filed. It is speculated that the carrier generation and transport at the depletion layer determines the effeciency of opto-electo conversion effciency in regioregular Polyhexylthophene but the bulk region between depletion layer and ohmic electrode. |
