ii ABSTRACT Wahidah Nur Lutfika Amini. 2018. The Influence of TiO2 Mass on TiO2-ZnO Nanocomposites as Photoanode on Structure Efficiency and Capacitance of Integrated Photosupercapacitors. Thesis Department of Physics Faculty of Mathematic and Natural Science State University of Malang. Advisors (I). Dr. Markus Diantoro M. Si (II) Drs. Abdullh Fuad M. Si. Keyword photosupercapacitor nanocomposite TiO2-ZnO structure efficiency capacitance. Photo-supercapacitor is a dual fungsional device that combines the energy conversion function of a solar cell such as DSSC with the energy storage capability of a supercapacitor. Research using single-semiconductor TiO2 SnO2 and ZnO as photoanoda materials still yields relatively low efficiency values. To increase the value of efficiency required research using semiconductor nanocomposites such as TiO2/ZnO. TiO2 is chosen because it has high thermal stability easy fabrication non-toxic low fabrication cost and has good optical properties. While ZnO is chosen because of its high electron mobility easy to process at low temperature and low fabrication cost. This study aims to determine the effect of addition of TiO2 masses on TiO2/ZnO nanocomposite on structures efficiency and capacitance of integrated photo-supercapacitors TiO2/ZnO nanocomposite pastes were firstly prepared for deposition on FTO-Glass substrate with 0.25 cm2 active layer. TiO2/ZnO nanocomposite paste was sintered at 100oC for half an hour and increase up to 200oC for half an hour and followed by dip coating process into dye solution containing 946 -carotene and quercetin. The sandwich structure of photosupercapasitors was fabricated with electrolyte I-/I3- in DSSC section and carbon tape as counter electrode ZnO as supercapacitor electrode which is deposited on aluminum foil and H3PO4 as electrolyte gel of supercapacitor section. The resulted photosupercapacitors were characterized using FTIR XRD SEM UV-VIS I-V source meter and DC LCR meter. The efficiency of DSSC and photosupercapacitor increase caused addition of TiO2 mass on TiO2/ZnO nanocomposite. The highest efficiency in DSSC was 3.06% and highest efficiency of the photosupercapacitor was 2.33%. The capacitance measured by the DC LCR meter after being illuminated by the solar simulator differs from that measured before being illuminated. The capacitance of photocupercapacitor after being illuminated was higher than before being illuminated. This fact proves that there is a conversion energy and stored electrical energy in the supercapasitor. ii
