Organometallic perovskite materials have been studied intensively since the pioneer work delivered by Prof. Miyasaka et al., which demonstrated its function as effective solar absorber. Recently, massive research works using various contact materials and device configurations-evolved from DSCs like mesocsopic, super-mesoscopic, ETA, to OPV-like planar heterojunction-have emerged during the past few years. Apartfrom the high efficiency received from perovskite solar cells, their stability and large area process are of great importance for future commerciallization. In this presentation, we present some novel designs and materials of organometallic hybrid perovskite solar cell using metal oxide materials for both electron and hole transporting layer (ETL and HTL). In conjunction with multicomponent or pseudohalide perovskites, their photovoltaic performance and stability are investigated. Efficiency over 15% can be obtained with such fully inorganic electrode device. The replacement of organic carrier transport materials by metal oxide is advantageous for providing robust device architecture and for the future development of perovskite tandem thin film solar cells.
