The synthesis of 4,4′-(9,9-dioctyl-9H-fluorene-2,7-diyl)bis(N,N-diphenylaniline) organic semiconductor and use of it as an interlayer on Au/n-Si diode

4,4-Difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) based BOD-Z-EN compound was used as an interfacial organic layer to fabrication of Au/BOD-Z-EN/n-Si/In diode. The electrical parameters of Au/BOD-Z-EN/n-Si/In diode such as ideality factor (n), barrier height (ΦB) and series resistance (Rs) have been investigated through current-voltage (I-V) studies at dark and under various illumination intensities to understand the effect of interlayer on the device properties. The values found for the n varied from 2.33 to 1.55 and the ΦB ranged from 0.86 eV to 0.90 eV as the illumination condition changed from dark to 100 mW/cm 2 . Series resistance (Rs) values calculated using Cheung's method were found to decrease with increasing illumination level. The forward bias I-V characteristics of the diode were explained by the space charge limited current (SCLC) theory. The main photovoltaic parameters such as open circuit voltage (Voc), short circuit current (Jsc) and fill factor (FF) were determined for various light intensity. The Au/BOD-Z-EN/n-Si/In diode exhibits a photovoltaic behavior with a Voc of 0.15 V and Jsc of 0.01 mA/cm 2 under 100 mw/cm 2 . Also, photosensitivity and photoresponsivity properties of the diode were determined. These all results indicate that Au/BOD-Z-EN/n-Si/In device can be used as photosensor in optoelectronic applications.
