1. A method for producing a paving slab for paving a traffic surface, the paving slab comprising:
a. a slab body with at least one recess,
b. a module arranged in the at least one recess, the module extending flatly along a module plane, and
c. at least one flat cover element aligned along the module plane and translucent at least in sections for protecting the module,
d. wherein the module is enclosed by the slab body and the at least one cover element in at least a liquid-tight manner,
e. the module comprising:
i. at least one flat photovoltaic layer aligned along the module plane for generating electrical energy,
ii. at least one flat luminous layer aligned along the module plane for illuminating a surrounding area of the module, and
iii. at least one flexible support element extending in a planar manner along the module plane, to which the at least one photovoltaic layer and the at least one luminous layer are applied by screen printing,
f. wherein the at least one photovoltaic layer and the at least one luminous layer each comprise a plurality of material layers aligned along the module plane and having different material compositions from each other,
g. wherein the at least one photovoltaic layer, the at least one luminous layer, the at least one flexible support element and the entire module are flexibly configured,
the method comprising:
h. providing the at least one flexible support element for the module of the paving slab,
i. screen printing the at least one photovoltaic layer and the at least one luminous layer of the module onto the at least one flexible support element,
j. placing the module in the recess of the slab body of the paving slab and
k. liquid-tight enclosing of the module in the recess with the cover element of the paving slab,
l. wherein enclosing the module comprises casting the cover element made of a plastic onto the module in the recess under high-frequency excitation of the plastic.
