Claim 0:
1. A solar reflecting film, comprising a substrate and a functional layer, the functional layer comprising a first reflecting layer, a barrier layer and a second reflecting layer stacked on the substrate in order;
wherein the barrier layer comprises a first barrier layer and a second barrier layer stacked on the first barrier layer;
the first barrier layer is metal fluoride, inorganic non-metallic oxide, metal oxide or a combination thereof;
the second barrier layer is metal oxides, metal nitrides, semiconductor doped compounds or a combination thereof; and
a material of the first barrier layer is at least partially different from that of the second barrier layer,
the barrier layer further comprises a third barrier layer between the first barrier layer and the second barrier layer, a material of the third barrier layer is metal fluoride, inorganic non-metal oxide, metal oxide, metal nitride, semiconductor doping compound, or a combination thereof, and
a material of the third barrier layer is at least partially different from that of the first barrier layer and that of the second barrier layer.
