Study the effect of nickel and aluminium doped ZnO photoanode in DSSC

Dye sensitized solar cells (DSSC) is one of the promising candidates which are efficient, low-cost, and clean hybrid molecular cell devices. Zinc oxide (ZnO) has been widely used as phoanode in DSSC due to its excellent charge conduction mechanism, yet still suffers from poor efficiency. In this study, aluminium doped ZnO (ZnO:Al) Ni (ZnO:Ni) were studied photoanode material using capacitance simulator (SCAPS ) simulation, electrolyte liquid considered a single solid p-type layer hole transporting materials. Both photoanodes have demonstrated better performance than pure small amount (Al) nikel (Ni) impurities added enhanced physiochemical properties films. A power conversion efficiency (PCE) 3.96% was obtained at 3 mol% ZnO:Al with optimized key parameters. These simulation results proved an opportunity improve DSSCs via doping engineering into photonaode.
