Abstract :Alignment nanofibers of polyinsert ignore into journalissuearticles values(o-toluidine);/polystyrene insert ignore into journalissuearticles values(POT/PS); were prepared by using an electrospinning method at different applied voltages insert ignore into journalissuearticles values(Vappl.); of 10, 15, and 20 kV. The effect of the applied voltage on the morphology and electrical properties of POT/PS nanofibers was studied. Morphology and diameters of the nanofibers were investigated via atomic force microscopy. insert ignore into journalissuearticles values(POT/PS);/Si hybrid solar cells were fabricated through the deposition of POT/PS nanofibers on Si wafers using the electrospinning technique. The current-voltage measurements of the device under dark conditions exhibited asymmetrical and rectifying behavior for the Al/insert ignore into journalissuearticles values(POT/PS);/Si/Al junction, thereby confirming the formation of diodes. Diode parameters, such as ideality factor n* and saturation current Io, were determined from the current density-voltage curves. The photovoltaic properties of the Al/insert ignore into journalissuearticles values(POT/PS);/Si/Al junction were studied under illuminated condition. Results revealed short-circuit current density Jsc = 1.45 mA, open-circuit voltage Voc = 596 mV, and solar cell efficiency = 3.04.
