A hermetic laser-assisted glass frit encapsulation, at a process temperature of 120 degrees C, was developed for perovskite solar cell application. The hermeticity and long-term stability of the sealing was examined based on standard tests for photovoltaic (PV) applications. Encapsulations using fluorine doped tin oxide (FTO)-coated glass substrates displayed 8.93 x 10(-8) atm center dot cm(3) center dot s(-1) ...
