Development of nanosized ZnO-PVA-based polymer composite films for performance efficiency optimisation of organic solar cells

Due to flexibility, environmental-friendliness, lower temperature growth, solution tunability, and flexibility of addition, organic solar cells (OSCs) are increasingly attracting prominence in photovoltaics. Despite these benefits, OSCs have a lower energy conversion efficiency than conventional solar-powered cells. As a result, increasing OSC effectiveness will inevitably be the focus. Using this idea, we developed the ZnO-integrated PVA nanocomposite (NCs) films to determine whether we could enhance their effectiveness. The NCs films were made utilising the Solution Casting Approach with a variety of ZnO nanoparticle concentrations in a PVA matrix. Each NCs film sample was examined using OSCs. OSC effectiveness varies significantly with and without using developed NCs films. When used on OSCs with the structure [carbon fibre]/(CuO/epoxy resin)/(ZnO/epoxy resin)/carbon fibre, the film with the appropriate weight percent of ZnO, 16.50%, and PVA, 83.50%, demonstrates a noticeable improvement in performance efficiency.
