PHOTOVOLTAIC MODULE PROVIDED WITH A H2O GAS PERMEATION BARRIER LAYER

A photovoltaic module including: several photovoltaic cells disposed side by side, and electrically connected to each other, an encapsulating assembly, configured to encapsulate the photovoltaic cells, and a barrier layer disposed at an interface between the encapsulating assembly and at least one photovoltaic cell, the barrier layer being configured to at least partially cover the at least one photovoltaic cell, and to have an O2 gas transmission rate lower than that of the encapsulating assembly, and a water vapor transmission rate less than or equal to 10-2 g/m2/day measured at 38° C. and 85% humidity level, so as to form a barrier to the transmission of water vapor and O2 gas.
