The use of direct deposition electrospinning process in ZnO nanofiber fabrication as double layer (TiO 2 /ZnO) DSSC: variation of solution flow rate

Abstract

The development of the use of Dye-sensitized solar cells (DSSC) types is increasingly studied. DSSC type solar cells are easy in fabrication and cheaper than silicon solar cells or thin layer type solar cells. DSSC engineering is manufactured by adding a semiconductor layer. Addition can be conducted by direct deposition of ZnO semiconductor layer on the TiO 2 nanoparticle layer by electrospinning process so as to create a double layer DSSC photoanoda.The liquid electro-jet spun from ZnAc/PVA on FTO glass coated TiO2 nanoparticles semiconductor was captured by direct deposition method using an electrospinning machine. This study was to investigate the effect of direct deposition of ZnO layers using electrospinning with variations in the distance of the tip to the collector and the flow rate. The results showed that the use of ZnO layers made by direct deposition at a flow rate 3μl / min produces a small diameter and uniform morphology. Small and uniform morphology allows ZnO nanofibers to have color absorption to produce a better DSSC double layer photoanode efficiency.
