Description: 
We study the optical response of CH3NH3PbI3 layers to light solicitation of the material under different environmental gas and temperature conditions. The measurements were performed in non-reactive (Ar or N2) and reactive (O2 or humid air) in the range 40-80° C crossing the tetragonal-cubic transition (50° C). With respect to truly inert Ar, the use of N2 not only assures the reversibility of the optical constants during thermal cycles but also improves the optical response of the material. While in N2 and Ar atmospheres the optical ...
