The film indicates a ferroelectric behavior with a remanent polarization of similar to 18.2 mu C/cm(2). Electronic parameters such as ideality factor and barrier height of the diode were calculated to be 3.80 and 0.75 eV, respectively. The photocurrent results in the reverse bias of the diode indicate that photocurrent under illumination is higher than the dark current. The diode exhibited a substantial visible-light photovoltaic effect. The capacitance-voltage and conductance-voltage measurements were carried out in the frequency range of 10 kHz-1 MHz. The observed decrease in the capacitance and increase in the conductance with the increasing frequency were explained on the basis of interface states. The interface states density of the structure was determined using Hill-Coleman method and observed to decrease with increasing frequency. The obtained results indicate that ferroelectric Bi3.25La0.75Ti3O12/P-type silicon junction is a new class of photoconductive devices with low-cost fabrication and high photoresponsivity  ISSN : 0927-0248  Journal Name : SOLAR ENERGY MATERIALS AND SOLAR CELLS  Volume : 133  Issue Number : 1  Publishing Year : 1435 AH 2015 AD  Article Type : Article  Added Date : Monday, August 21, 2017  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email F Yakuphanoglu Yakuphanoglu, F Investigator Doctorate   A Tataroglu Tataroglu, A Researcher Doctorate   A.A Al-Ghamdi, Al-Ghamdi, A.A Researcher Doctorate   R.K Gupta, Gupta,, R.K Researcher Doctorate ramguptamsu@gmail.com Y Al-Turki Al-Turki, Y Researcher Doctorate   Z Serbetci Serbetci, Z Researcher Doctorate   S Bin Omran Bin Omran, S Researcher Doctorate   F El-Tantawy El-Tantawy, F Researcher Doctorate   Files File Name Type Description  42727.pdf pdf   Back To Researches Page
