Abstract: Hybrid organic/inorganic perovskites have attracted a lot of attention since they were first introduced in a working photovoltaic device. They present high efficiencies, an inexpensive fabrication cost, and the possibility to fabricate flexible PV devices. However, they still present some issues that need to be addressed, such as chemical or structural instabilities under ambient conditions. In order to better understand the structural stability, and the role played by the interaction between the organic cation and the inorganic framework, we studied the structural and optoelectronic properties of perovskites of the family FAxMA1-xPbI3 at different pressures (up to 15 GPa) and temperatures (10 to 385 K). We investigated this material by noninvasive optical spectroscopy means, such as photoluminescence (PL), Raman and ellipsometry.
