The effect of the Al concentration on efficiency of the hybrid AnE-PVstat:Al-doped ZnO nanocrystal solar cells

Abstract In the present study, Al-doped ZnO nanoparticles (AZO) with different Al concentration (0.2%, 0.6%, 5%) as an acceptor are immersed in the anthracene containing poly( p -phenylene-ethynylene)- alt -poly( p -phenylene-vinylene) (PPE-PPV) denoted AnE-PVstat network polymer as donor component to improve the photovoltaic performance. The absorption spectra of the AnE-PVstat:AZO(%) are investigated and deconvoluted based on Franck-Condon analysis. The absorption spectra in nanocomposites thin films showed a slight red shift compared to the pristine polymer. This move may emerge from a chain-chain contact change through the arrangement of rod-like chains of quasi-coupled atoms by means of the nanoparticles diffusion into the system and the variation of aluminum doping concentration. Therefore, we fabricated devices with an AnE-PVstat:AZO blend. Moreover, the conduction types are estimated and used to determine the optoelectronics parameters through theoretical models. The photovoltaic performances of the hybrid solar cells are evaluated. The hybrid photovoltaic device of AnE-PVstat:AZO(0.2%) performance exhibited an improved device efficiencies as high as 0.34%, with J sc = 1.61 mA/cm 2 , V oc = 0.81 V and a FF = 0.26 under illumination with 100 mW/cm 2 light intensity.
