Abstract

Organic/inorganic hetero junction solar cells were fabricated by deposition of PAni.CSA/PEO nano fibers on TiO2 n-type layer by using electrospinning technique. The current-voltage (I-V) measurements of the device under dark conditions exhibits asymmetrical and rectifying behavior for ITO/TiO2/PAni.CSA.PEO/Al junction that confirms the formation of diode. The diode parameters such as rectification ratio Rr, saturation current Io, ideality factor n* are determined from I-V curves. The photovoltaic properties of ITO/TiO2/(PAni.CSA/PEO)/Al junction were studied under illumination condition, and found the short circuit current density Jsc= 0.82 mA, open circuit voltage Voc = 485mV, and solar cell efficiency =0.902 after annealing.
