Photovoltaic module frontsheet and backsheet

A photovoltaic module, comprising:

• at least one solar cell;
• an encapsulant encapsulating the at least one solar cell,
• wherein a thickness of the encapsulant is 0.5 mm to 1.8 mm;
• and
• a frontsheet adjacent to the encapsulant,
• wherein the frontsheet includes
• a glass layer,
• wherein a thickness of the glass layer is 2.5 mm to 4 mm,
• a polymer layer
• wherein the polymer layer includes a fluoropolymer selected from the group consisting of ethylene tetrafluoroethylene (ETFE), polyvinylidene fluoride (PVDF), tetrafluoroethylene-hexafluoropropylene copolymers (FEP), tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride copolymers (THV), polyvinyl fluoride (PVF), and blends thereof, and
• wherein a thickness of the polymer layer is 0.01 mm to 0.5 mm, an adhesive layer directly adhering the glass layer to the polymer layer,
• wherein the adhesive layer is selected from the group consisting of thermosetting polyolefin, thermosetting polyolefin encapsulant material, thermosetting ethylene-vinyl acetate (EVA), EVA encapsulants, thermoplastic polyolefin (TPO) and hybrids and combinations thereof,
• wherein a thickness of the adhesive layer is 50 micrometers to 700 micrometers, and
• wherein the glass layer of the frontsheet is adjacent to the encapsulant encapsulating the at least one solar cell,
• wherein the photovoltaic module is configured to be installed on a roof deck, and
• wherein, when the photovoltaic module is installed on the roof deck, the polymer layer is a top layer opposite the roof deck.
