Morphology and Optical Properties Analysis of Cu2+ Doped ZnO for Preparation Dye Sensitized Solar Cell (DSSC)

This research reported Cu2+ un-doped (pure) and doped ZnO semiconductors with variations in concentrations of 3%, 4% 5% through the sol gel method which aims to determine morphology optical properties has been investigated. In addition, film was coated using doctor blade addition chlorophyll as a dye sensitizer. Morphological elemental content tests were carried out SEM EDS. The analyzed by taking Transmittance data UV-Vis Spectrophotometer. analysis 9900X magnification showed that all samples had small grain sizes pores formed uneven (heterogeneous). EDS higher concentration zinc weight than oxygen. Spectrophotometer shows transmittance value without is lower Dye. affects ZnO. added chlorophyll, absorbance value, so decreases. maximum
