Solar laminates as laminated safety glass
Solar modules, with the properties of laminated safety glass, comprising a laminate containing a) a glass pane b) at least one solar cell unit that is located between two PVB-based films, and c) a rear covering and at least one of the PVB-based films has a tensile strength of at least 16 N/mm 2 , are suitable for use as a facade component, roof surface, winter garden covering, soundproofing wall, or as a component of windows.
1 . A laminated safety glass solar module comprising a laminate of
a) a glass pane
b) at least one solar cell unit that is located between two PVB-based films, and
c) a rear covering, wherein at least one of the PVB-based films has a tensile strength of at least 16 N/mm 2 .
2 . A solar module according to claim 1 , wherein at least one of the PVB-based films has a melt flow index of 15 to 40 g/10 minutes, measured at a load of 2.16 kg and at 150° C.
3 . A solar module according to claim 1 , wherein at least one of the PVB-based films in a glass/glass laminate has compression shear adhesion on air/air glass surfaces of 10 to 30 N/mm 2 .
4 . A solar module according to claim 1 , wherein at least one of the PVB-based films in a glass/glass laminate has compression shear adhesion on tin/tin glass surfaces of 10 to 25 N/mm 2 .
5 . A solar module according to claim 1 , wherein the rear covering is made from glass, plastic, metal, laminated glazing and/or insulating glazing.
6 . A solar module according to claim 1 , wherein at least one of the two PVB-based films has soundproofing properties.
7 . A solar module according to claim 1 , wherein current is delivered to the solar cell units via conductor paths placed between the PVB-based films.
8 . A process for producing a solar module in the form of a laminated safety glass, comprising:
making a body of
a) a glass pane as the front side,
b) at least one solar cell unit that is located between two PVB-based films, at least one film having a tensile strength of at least 16 N/mm 2 , and
c) a rear covering,
by lamination of the body under elevated or reduced pressure and at elevated temperature.
9 . A process according to claim 8 , wherein lamination is carried out at a reduced pressure of 0.01 to 300 mbar and at a temperature of 100 to 200° C.
10 . In a facade component, roof surface, winter garden covering, soundproofing wall, balcony or parapet element or as a component of windows comprising at least one solar module, the improvement wherein said solar module is a module according to claim 1.
