The synthesis of mesoporous titania films usually requires sintering at high temperature of 450–550 oC prior to use, which may cause the limitation of perovskite solar cells to be deposited on flexible substrates or to be compatible with fabrication processes in multi-junction solar cells. In this subproject, we would like to propose two strategies to develop new scaffold or interlayer materials for low-temperature processable perovskite solar cells. (i) The first part is related to the bulk-intermixing (BI)-typed perovskite CH3NH3PbI3/TiO2 nanorod hybrid solar cells, which can be used to replace high-temperature sintered mesoporous TiO2 films. (ii) The second part is related to the replacement of the high-temperature TiO2 compact layer with solution-processable atomic layered TiO2 nanosheets.鈣鈦礦太陽能電池二氧化鈦奈米材料低溫製程Perovskite solar cellTiO2 nanomaterialslow-temperature processes
