Abstract The compounds with perovskite structure have been extensively studied to be used in photovoltaic cell architectures due to the high efficiency in the conversion of solar energy. In this project, it is intended to synthesize organic/inorganic hybrid compounds with the general formula APbX3, where A = Cs or CH3NH3 and X = I, Cl or Br. These compositions present structural phase transitions in different temperature range which directly influence the band gap energy value. The thermal, structural, morphological and electric transport properties will be studied according to the space group symmetry of each compound and compared with computational simulations. Interface phenomena (APbX3 - moisture) that lead to the perovskite structure degradation will also be studied regarding to the space group symmetry. (AU) | |
