Organic-inorganic hybrid heterojunction solar cells containing perovskite CH3NH3PbI3 using lead phthalocyanine (PbPc) as a hole-transport layer was fabricated and characterized. The optical behavior indicates the phase of PbPc with H-aggregation. The X-ray diffraction patterns showed molecular ordering as a monoclinic structure in the H-aggregation. Introducing of PbPc as the hole-transport layer on the perovskite solar cell improved the stability of photovoltaic performance for 2 weeks under air atmosphere.
