| Outline of Final Research Achievements |
14-group-element-based solar cells with DA interpenetrated-junctions were developed in the present work. Various TiO2/CH3NH3PbI3-based photovoltaic devices were fabricated and characterized. Elemental doping to the perovskite structure and TiO2 were studied by experiments and theoretical calculations, as follows: Cs and Rb doping to the CH3NH3 positions for stability of the structure; Ge, Sn and Sb doping to the Pb positions for improvement of the semiconducting properties; Cl and Br doping to the I positions for enhancement of carrier mobility. PCBM:P3HT:ZnPc DA interpenetrated-junction solar cells with an inverted structure were also fabricated, and the short-circuit current density of the solar cells were improved by the ZnPc addition and Ge dot formation. Conversion efficiencies of spherical Si solar cells coated with SnOx:F anti-reflection thin films were also improved by controlling the interfacial structures. Guidelines for device design were constructed for the new solar cells.
