- Methylammonium lead halide perovskites have been intensively studied [1-9]as promising photoabsorption and carrier transporter materials in solar cells because of their excellent semiconducting properties, [10,11]broad range of light absorption, and high extinction coeffi cient. [5,12]Hybrid solar cells with 10.9% power conversion effi ciency have been fabricated using a meso-superstructured organometal halide perovskite, which triggered a lot of attention in the solar cell research community; the perovskite layer acts as both the light harvester and the hole conductor in the devices.  The bandgap of perovskites can be easily adjusted by incorporating metal cations,inorganic anions, or organic ligands. Methylammonium lead halide perovskites also have the advantage of low-temperature (ca. 100 °C) solution processibility. Because of all these advantages, the power conversion effi ciencies (PCEs) of perovskite- based solar cells have reached 15.4% in a solar cell that incorporates a vacuum-deposited perovskite layer and a TiO 2 layer. Although the PCE of perovskite solar cells has been increased remarkably, few reports [7,16,17]have considered solution- processed planar heterojunction (SP-PHJ) structure solar cells without using a mesoporous or compact semiconducting metal oxide (e.g., TiO 2) layer processed by high-temperature sintering, and the SP-PJH solar cells to date have shown lower PCE than those with a mesoporous or compact TiO 2 layer
