Outline of Final Research Achievements

In this study, it was examined to optimize both the surface/interface characteristic and the surface band structure to improve photoelectric conversion efficiency of the organic inorganic hybrid solar cells by controlling the surface/interface nanostructure of perovskite and TiO2 by the development of the co-dope processing technique of the cation and the anion using the sol-gel method that was a chemical treatment method and the low-temperature plasma treatment method and the ion-implantation that were a physical treatment method. Using the developed belljar type low-temperature plasma apparatus attached to the ion-implantation system we investigated the surface modification effects by the physical and chemical treatment such as the low temperature plasma processing and the ion-implantation for each interlamellar interface of the TiO2 layer, perovskite layer and p type organic semiconductor in the solar cell for the purpose of the high efficiency of the perovskite type solar cells.
