Özet
This paper presents in-depth analysis of the current-voltage (I-V) and capacitance-voltage
(C-V) characteristics of identically prepared Au/Pyrene(C16H10)/n-Si hybrid organic-oninorganic semiconductor photovoltaic cells (total 43 diodes). The barrier heights, ideality
factors and reverse bias saturation currents of all devices were extracted from the electrical
characteristics. The mean barrier height, mean ideality factor and mean saturation current
from I-V measurements were calculated as 0.79 ± 0.01 eV, 1.40 ± 0.08 and (1.01 ±
0.46)x10-8 A, respectively. Also, the photoelectric (I-V) and photocapacitance (C-V and
conductance (G)-voltage (V)) characteristics of the Au/Pyrene/n-Si device under 100
mW/cm2
light illumination were investigated. It has been seen that the light illumination
increases strongly the current, capacitance and conductance values of the device due to
electron-hole charge pair generation. The C-V and G-V characteristics under illumination
have shown a non-monotonic dependence of capacitance on frequency giving rise to a
peak. This is attributed to the existence of electrically active traps. The open circuit
voltage and short circuit current of the Au/Pyrene/n-Si device were extracted as 80 mV
and 30 µA, respectively.
