Abstract
Recently, dye-sensitized photoelectrochemical solar cells (DSSC) is regarded as a bright candidate in the search due to their low-fabrication cost and environment-friendly solar cell. Also, Dye-sensitized solar cells (DSSCs) based on nanocrystalline TiO2 have exhibited solar efficiencies of over 16% and remain one of the most rising substitute for cost-effective solar energy conversion devices at high temperature process (450℃). Zinc oxide (ZnO), Al doped Zinc oxide (AZO) are similar to TiO2 that has a wide band gap and electron affinity. So, the ZnO, AZO materials will be substitute for an alternative material of TiO2 as the DSSC application. We investigate on structural and electrical properties of ZnO, AZO, SnO2 dyesensitized solar cells (DSSCs) fabricated by using both ZnO, AZO, SnO2 nanoparticles for electron transport layer (ETL) at low temperature (200℃) and Pt catalyst deposited on ITO/glass by using RF magnetron sputtering. According to hydropolymer (P.E.G and P.E.O) ratio in mixed ZnO, AZO, SnO2 nanopowder-DI water solution, the DSSC maximum parameters of the short circuit current density (Jsc), the open circuit potential (Voc), fill factor (ff), and efficiency (η) were measured to be 5.10 mA/cm2, 0.61V, 0.46, and 1.42%, respectively.
