Chapter 1

High Efficiency Mesoscopic Organometal Halide Perovskite Solar Cells

Since the report on a long-term durable and high efficiency all-solid-state perovskite solar cell employing a CH3NH3PbI3-sensitized mesoporous TiO2 film in 2012, a surge of interest in perovskite solar cells has been received due to their super photovoltaic performance along with the unconventional opto-electron properties of halide perovskite containing organic cations. As a result, a power conversion efficiency (PCE) of 20.1% was certified at the end of 2014 using mesoscopic perovskite solar cell architecture. In this chapter, high efficiency perovskite solar cells with the embodiment of mesoporous or nanostructured oxide layers are described together with a brief summary on the emergence and progress of perovskite solar cells. The methodologies for high quality organolead halide perovskites with mesoscopic structure are discussed. The opto-electronic properties of three-dimensional (3D) nanocuboid and one-dimensional (1D) nanowire perovskites are studied, and the electron injection behavior in 3D and 1D nanostructured oxide layers is compared. Finally, the factors affecting IV hysteresis are also investigated and analyzed by impedance spectroscopy.
