Compounds with organic-inorganic perovskite structure continues to be in the photovoltaic focus area because these materials have the abilities to combine the properties of inorganic part (high carrier mobility, wide range of bandgaps) and those of organic part (high efficiency luminescence, mechanical properties [1,2]. In the present work we report the preparation of the organic-inorganic perovskites CH3NH3PbX3, (X=Br, Cl, I) by low temperature (130°C) and autogenous pressure hydrothermal route and characterization by X-ray powder diffraction and optical UV-VIS spectroscopy.
