Abstract
Disclosed is a sheet for use as a packaging material having a low percentage thermal shrinkage, outstanding flexibility and outstanding properties as a packaging material for solar cells. The sheet for use as a packaging material for solar cells according to the present invention is a resin sheet having air spaces obtained by the hot-melt bonding of a portion of a dispersed hot-bonding resin powder, wherein the apparent density of the sheet is no less than 20(%) and no more than 70(%) of the net density of the hot-bonding resin, such that the sheet is adequately flexible.
Claims7
An encapsulant sheet for solar cells, the encapsulant sheet comprising hot-bonding resin powders which are partially melted and bonded to each other to maintain pores,
- wherein the encapsulant sheet has an apparent density that is 20% to 70% of a net density of the hot-bonding resin,
- wherein the hot-bonding resin comprises an ethylene copolymer containing 60 wt % to 90 wt % of ethylene, and
- wherein the hot-bonding resin has a melt mass-flow rate of 1 g/10 min to 50 g/10 min.
