PROBLEM TO BE SOLVED: To provide a solar cell sealing film for a solar cell module constituting a photovoltaic power generation facility having a system voltage of 600 V or higher, which can suppress occurrence of PID phenomenon.SOLUTION: The solar cell sealing film for a solar cell module constituting a photovoltaic power generation facility having a system voltage of 600 V or higher consists of a cross-linked cured film of a composition containing an ethylene-polar monomer copolymer and a crosslinking agent. The product (&rgr;v×t) of the volume resistivity (&rgr;v[&OHgr; cm])(conforming to JIS K6911-1995) of the solar cell sealing film at a temperature of 25°C after crosslinked curing, and the thickness (t[cm]) of the solar cell sealing film is 5.0×10or more. A selection method of the solar cell sealing film for selecting a solar cell sealing film having the product &rgr;v×t is also provided. |
