Abstract

The efficiency obtained by using TiO 2 semiconductors is still low due to interfacial charge recombination. In this research, two coating methods were carried out, namely doping and bilayer using ZnO as a semiconductor to reduce recombination to collect charge and increase the efficiency of Dye-Sensitized Solar Cells. The use of UV-DRS in this study to see the band gap shows a decrease in the band gap after doping and bilayer processes. The XRD used in the study to look at the phase and molecular structure showed that the intensity of TiO 2 was lower due to doping and bilayer. The dye used is Quercetin which is polymerized to increase conjugated bonds. To see the polymerized Quercetin tested using FTIR. In the quercetin crosslinker polymerization process varied to 1.5 ml; 2.5 ml; and 3.5 ml to see how many conjugate bonds are formed so that the efficiency obtained is also high. Efficiency measurement using a multimeter. Based on the results of this study, it was found that the efficiency of solar cells increased. In the doping process, the highest efficiency was 11.3%, while the highest efficiency in the coating process was 9.1%.

期刊介绍： RASĀYAN Journal of Chemistry [RJC] signifies a confluence of diverse streams of chemistry to stir up the cerebral powers of its contributors and readers. By introducing the journal by this name, we humbly intent to provide an open platform to all researchers, academicians and readers to showcase their ideas and research findings among the people of their own fraternity and to share their vast repository of knowledge and information. The journal seeks to embody the spirit of enquiry and innovation to augment the richness of existing chemistry literature and theories. We also aim towards making this journal an unparalleled reservoir of information and in process aspire to inculcate and expand the research aptitude.
