REAR SURFACE PROTECTIVE SHEET FOR SOLAR CELL

摘要

The present invention provides a rear-surface protective sheet for solar cells, the rear-surface protective sheet having a function of suppressing temperature increase in solar cells. The present invention provides a rear-surface protective sheet for solar cells that is disposed on a rear surface of a solar cell, comprising at least one heat conversion layer containing a heat conversion filler having a function of converting thermal energy to vibrational energy to consume the thermal energy,
the heat conversion filler in the heat conversion layer having a density of 3 to 35 g/m 2 .
