Optical Properties Of Blend Polymers Of Polyvinyl AlcoholPoly O-Toluidine And Their Solar Cells Application

ABSTRACT The chemical polymerization method was used to prepare polyo-toluidine POT which is characterized by FTIR XRD and SEM and then the blend polymers of PVAPOT were investigated by mix different volume ratios of polymers as 11 12 21 PVAPOT. The optical properties of the blend polymers were studied after deposited it on the glass substrate by a spin coating method and this study appeared the energy gaps of blend polymers increased with increasing the amount of POT. The J-V curves of prepared photovoltaic devices PVAPOTn-Si which were measured under dark and illumination 100 gave information about prepared devices performance whereas the better power conversion efficiency was recorded at the ratio 12 PVAPOT to be 1.567 with and FF equal to 13.3647 0.32 0.36634 respectively
