This extended abstract introduces a method of encapsulation at low temperature that uses a commercial sheet composed of ethylene-vinyl acetate (EVA), in order to protect perovskite layers from humid environments and UV radiation. MAPbI3 thin films were deposited over a batch of glass substrates using spin coating techniques, half of the batch being encapsulated. Then they were exposed to solar radiation in an environment that had a relative humidity (RH) from 60 to 80%. The degradation processes were characterized by microscope imaging, optical ellipsometry and Fourier-transform infrared spectroscopy (FTIR) techniques. Preliminary results indicate that the EVA encapsulated samples, unlike their non-encapsulated counterparts, remained stable above 350 hours under solar radiation. Also, from the FTIR study performed, it can be inferred that the vibration modes at 3181 cm-1 (N-H stretch), 3124 cm-1 (N-H stretch), 1465 cm-1 (symmetric NH3+ bend) can be used as indicator peaks of the perovskite degradation caused by UV light.
