Abstract
A concrete having a smooth surface, which is wholly or partly coated with a polymer film obtained by polymerisation under the action of radiation, where the film is itself wholly or partly coated with a thin photovoltaic film.
Claims19
A method for manufacture of a photovoltaic concrete, comprising:
- obtaining a concrete;
- applying a composition containing monomers and/or reactive unpolymerised prepolymers over all or part of a surface of the concrete;
- polymerising this composition under the action of radiation, so as to obtain a polymer film wholly or partly covering the surface of the concrete;
- applying by cathodic sputtering, by chemical deposition in the vapour phase, by ionic deposition, by plasma deposition, by electron bombardment, by laser ablation, by epitaxy by molecular jets, or by thermo-evaporation, at least one thin photovoltaic layer directly on to the polymer film.
