The overall objective of the ETFE-MFM Proposal is the development, evaluation and demonstration of a flexible multifunctional ETFE module for architectural façade lighting. The aim of this proposal is to provide a PV module with embedded additional functionalities designed to be used in ETFE textile architecture for BIPV applications.ETFE-MFM concept is based on the integration of different technologies creating a self-contained building element formed by: ETFE architecture, photovoltaic (PV) technology, illumination devices and flexible integrated circuits (IC). This new concept of multifunctional PV module will be able to work as a stand-alone or grid connected system. The solar energy supplied to the lighting devices will open new architectural façade lighting possibilities due to saving cost in the high energetic demand requested by this type of devices.The basic idea behind the development of ETFE-MFM is to enhance the use of building integrated photovoltaic (BIPV) elements in construction industry, as well as to provide new architectural façade lighting possibilities. The ETFE-MFM basic principles represent relevant innovative elements which are based on the combination of:- A novel attractive textile architecture based on ETFE as building material. The physical characteristics of ETFE allow construction cost savings by reducing greatly the weight of the structure whilst providing the same or even higher level of stability.- PV device, which acts as an electrical generator and shading during daylight, and supply the energy requested by the façade lighting devices at night, reducing the overall energy costs of the building.- Illumination devices, based on LED-RGB and OLED technologies, embedded on the module.- Flexible IC, which acts as individual module control of the PV device, providing the maximum power point (MPP) of the cells, as well as the control of the LED devices through wireless technology.
