Hence, ionic electrolyte and blend polymer composite electrolyte helps in ion regeneration and improving the performance of the device. Introduction of metal nanoparticles in the polymers such as the PMMA, PVDF provides this enhancement of performance. Nanoparticles are manufactured in an eco-friendly manner and characterized by UV and XRD. In this work we present the possibility that could be explored with the incorporation of nanoparticles and also see the synthesis process of green nanoparticles. The excitons dissociation in these devices could increase with the intro- duction of nanoparticles. They exhibit a near field surface plasmon resonance effect which couples with the existing photoactive layer, increasing the absorption cross section. We propose that these non-toxic and bio-friendly nanoparticles are very beneficial in our quest of green energy. Keywords: nanoparticle; photoelectronic devices; polymer; biofriendly Introduction Nanoparticles are very important in various aspects of technology as they have provided an enormous range of applications. In physics, we study the structural properties of these nanoparticles and the many ways these properties can prove useful for different purposes. In solar cells, these nanoparticles have endowed
