STEELPV project proposes to functionalize low cost industrial steel as direct substrates for photovoltaic devices. Different steel substrates will be used (stainless steel different from solar grade stainless steel, galvanized/aluminized cold rolled low carbon steel and bare cold rolled low carbon steel) taking into account industrial implementation feasibility of the steel/PV systems. Steels compatibility with the thin film PV deposition processes selected, based on silicon, chalcopyrite and organic technologies, will be carried out through the development of intermediate layers using non-vacuum and vacuum strategies.
The viability of steel/Intermediate layer solutions will be shown through different prototypes (including 30cm x 30cm flat panels, 18cm x 180cm flexible sheets and 30cm wide coils) using different deposition technologies that could be easily integrated into a steel coating line. At the end of STEELPV project, a portfolio of value added steel products will be ready, enabling steel partners direct access to the photovoltaic industry.
The products developed in STEELPV will be suitable for different steel thicknesses what could drive to flexible (used to cover geometrical complex structures already existing) or semi-rigid (used as mechanical part of the structure) final applications. Sectors such as building envelopes (façades and roofs) of both new and existing buildings (residential, industrial), road infrastructures and transports will take benefit of the STEELPV developments.
The project has received funding from the Union’s Research Fund for Coal and Steel (RFCS) research programme under grant agreement nº RFSR-CT-2014-00014.
