Characteristics of ZnO nanofiber in double Layer (TiO2 / ZnO) DSSC results of direct deposition electrospinning manufacturing: Variation of tip to collector distance

Abstract

Solar energy is obtained from sunlight. Solar cells are harvesters of solar energy that are converted into electrical energy through the photovoltaic process. One of solar cell types are Dye-sensitized solar cells (DSSC) based on double layer photoanode which is very attractive to researchers because of its high performance, cheaper, and availability of mass production. The two-layer TiO2-ZnO semiconductor obtained with the nanofiber ZnO semiconductor was deposited directly with the TiO2 nanoparticle semiconductor. The addition of the nanofiber ZnO semiconductor layer is known to reduce the semiconductor band gap value.This present study is to determine the effect of direct deposition of the ZnO layer using electrospinning with variation of the tip distance of the collector. The results showed that the use of ZnO nanofiber layers made by direct deposition on the tip distance is 7 cm to the collector, which produced a small diameter size and uniform morphology. Small and uniform morphology allows DSSC to have better electron excitation. This is directly proportional to the high efficiency of DSSC double layer.
