NOVELTY - The rigid or flexible photovoltaic module (10) comprises an electronic device, a polymeric material present in the form of a monolayer film in intimate contact with a surface of the solar cell, and a glass cover sheet. The polymeric material comprises an ethylene multiblock copolymer, a free radical initiator (0.05 wt.%), a co-agent (0.05 wt.%), and a scorch inhibitor (0.01-1.7 wt.%). The ethylene multiblock copolymer has a molecular weight distribution of greater than 1.3, a density of less than 0.90 g/cc, a 2% secant modulus of less than 150 mPa, and a melt point of less than 125degrees C.    USE - The component deals with the rigid or flexible photovoltaic module having a solar cell.    ADVANTAGE - The rigid or flexible photovoltaic module has high efficiency, strong adhesion to the solar cell and substrates, good transparency and high resistance to moisture, air and mechanical shock, avoids the mechanical stress resulting from polymer shrinkage, and is simple and cost-effective to manufacture.
