The ESTETiCO project addresses the challenge of developing colored photovoltaic modules for Building Integrated Photovoltaics (BIPV), combining high energy performance with the aesthetic requirements of modern architecture. Conventional coloring techniques reduce the amount of light reaching the solar cell, leading to lower conversion efficiencies. To overcome this limitation, ESTETiCO investigates the use of polymer encapsulants incorporating fluorescent molecules (fluorophores), capable of recovering part of the absorbed light through fluorescence emission and redirecting it toward the active photovoltaic material. This innovative approach aims to produce visually appealing photovoltaic panels while maintaining efficiencies comparable to conventional silicon technologies. By bringing together partners with complementary expertise in photovoltaics, advanced materials, fluorescence engineering, and device characterization, ESTETiCO is developing sustainable solutions that enable seamless integration of solar energy generation into the built environment.
