Abstract
Official abstract text for this publication.
Disclosed is a multilayered weatherable film for a solar cell, which has superior elongation change rate, strength change rate and haze and thus is suitable for use in a solar cell, and includes a hard layer having a polyester or copolyester polymer resin and a soft layer having polybutylene terephthalate containing polytetramethylene ether glycol, which are regularly or irregularly laminated in a multilayer form.
First claim
Opening claim text (preview).
The invention claimed is: 1. A weatherable film for a solar cell, consisting of: a hard layer and a soft layer laminated and alternately stacked in a multilayer form with said hard layer and said soft layer each contained in said multilayer form multiple times, wherein the hard layer consists essentially of a polyester or copolyester polymer resin having a crystallinity of 75-95% and the soft layer consists essentially of a polybutylene terephthalate glycol copolymer containing 10…
