Abstract: An encapsulant sheet includes a material formed from an ethylene/C4-C8α-olefin copolymer having a resin volume resistivity (VR) from greater than 1×1014Ω cm at 60° C. to less than 1×1016Ω cm at 60° C. and from 0.01 wt % to 0.2 wt % of an ion scavenger. The encapsulant sheet has a transmittance greater than 91%. A photovoltaic module (10) includes a front encapsulant sheet (12a) and a rear encapsulant sheet (12b) composed of the material. The photovoltaic module (10) has a power loss after potential induced degradation (PID) test from 0.05% to less than 5%.
