Abstract
The current–voltage characteristics of the organic/inorganic fluorescein sodium salt FSS/n-Si heterojunction diode under dark and illumination have been investigated. The diode parameters such as barrier height and ideality factor were determined. The ideality factor n value at different temperatures was found to be in range from 6.30 to 4.56. These values suggest that the FSS/n-Si heterojunction diode is a non-ideal contact. A space charge limited-conduction (SCLC) mechanism, where current increases superlinearly, i.e, I∝Vm>2I∝Vm>2, takes place in the diode. The photocurrent properties of the diode under various illuminations have been investigated. The photocurrent in the reverse direction is strongly increased by photo-illumination.
