Methylammonium lead triiodide perovskite solar cells have emerged as credible contenders to conventional p-n junction photovoltaic devices. Perovskite material involves low cost precursors, capable of being processed via a variety of scalable methods and deliver high power conversion efficiencies comparable to thin film and crystalline silicon solar cells.1-2<\/sup>\u00a0Using CH3<\/sub>NH3<\/sub>PbI3<\/sub>\u00a0perovskite as an absorber layer and molecularly engineered functional hole transport material, power conversion efficiencies (PCE) over 22% were obtained.3-5<\/sup>\u00a0However, a fundamental understanding of the working principle of perovskite solar cells, and stability of the material is still lacking. In addition, an anomalous hysteresis behavior in the current-voltage characteristics is often reported in perovskite solar cells possibly related to ion migration and imbalanced extraction of charges. In this talk we present various deposition methods for perovskite absorbing layer, and the synthesis and characterization of novel hole transporting materials.<\/p>\n (1). Lee, M.
