Abstract This paper aims to investigate the structural, optical, electronic and electrical properties of PVA/PVP blend and PVA/PVP blend doped with In2O3 and Cr2O3 nanoparticles to use it for various flexible electronics devices like solar cell, sensors diodes, electronics gates, transistors have low cost, high corrosion resistance, low energy gap, flexible, low weight, high optical and electrical conductivities. The results indicated that absorbance of PVA/PVP blend improved about 30% and 34 r2O3 nanoparticles concentrations. The energy gap value of PVA/PVP blend was reduces with the increase of In2O3 and C from 2.8 eV of PVA/PVP to 1.2 eV and 1.77 eV as In2O3 and Cr2O3 nanoparticles concentrations increase. Doping PVA/ PVP with In2O3 and Cr2O3 nanoparticles enhance the optical constants, electronics parameters and electrical conductivity. The obtained results showed that the doping PVA/PVP blend with In2O3 and C r2O3 improved the structural, optical, electronic and electrical characteristics which make the (PVA/PVP/In2O3) and (PVA/PVP/Cr2O3) nanocomposites are promising materials for flexible optoelectronics fields in the development of electronics applications.

1 Introduction In latest years, organic doped with inorganic nanoparticles have been focused for its good physical, chemical properties and huge potential fields in nanoelectronic devices [1]. Polyvinyl alcohol is one of the most universal polymers of everyday life that are distinguished by their extensive applications related to its attractive physical and chemical characterization, good thermal stability, good mechanical strength, excellent chemical resistance and high water solubility. PVA is a semicrystalline substance that displays certain physical characteristics resulting from the effect of crystal amorphous interfacial. Its structure shows a backbone of carbon with groups of hydroxyl bonded to methane carbons. The groups of hydroxyl may be a hydrogen bonding source [2]. PVP is a water soluble and it has more attention because of its extensive field in the nanostructures synthesis. * Ahmed Hashim [email protected] 1

It displays atypical complexing and colloidal characteristics, and has been comprehensively used as a protective colloid in pharmaceuticals and medicine, solubility promoter, viscosity improving agent and coating material or film forming [3]. Indium oxide ( In2O3) is a technically very important transparent conductive oxide (TCO) substance. I n2O3 is an n-type semiconductor with energy gap in the range from 3.6 to 3.72 eV. The In
