ENERGY HARVESTING IN CITIES WITH TRANSPARENT AND HIGHLY EFFICIENT WINDOW-INTEGRATED MULTI-JUNCTION SOLAR CELLS

Descripción del proyecto

Las ventanas solares alcanzan un nuevo nivel

Aunque ya se pueden fabricar celdas fotovoltaicas transparentes para ventanas, hasta ahora no han alcanzado una eficacia suficiente en la conversión de la luz solar en electricidad. El proyecto CITYSOLAR, financiado con fondos europeos, se propone cambiar esta situación combinando dos tecnologías fotovoltaicas en una configuración en tándem. En particular, CITYSOLAR desarrollará celdas fotovoltaicas de unión múltiple optimizadas para absorber diferentes longitudes de onda de luz solar mediante la combinación de unas nuevas celdas fotovoltaicas de perovskita, que poseen una separación energética alta, con celdas fotovoltaicas orgánicas, que están exentas de fullerenos y tienen una separación energética baja. Esto allanará el camino hacia unas celdas fotovoltaicas altamente transparentes que absorban la luz ultravioleta e infrarroja, pero no la luz visible, permitiendo alcanzar una eficiencia de conversión superior al 15 %.

Objetivo

Transparent photovoltaics (TPV) possesses a huge untapped potential in the harvesting of solar energy where it readily can be embedded in buildings applications worldwide to significant reduce CO2 emissions, and support the needed development of nearly zero-energy buildings. TPV will increase the utilization of renewable energy directly where it is needed, and play a crucial role for the sustainable transformation of the energy sector in large cities. Using conventional photovoltaics, however, it is not possible to fabricate TPV elements without severe losses in efficiency and/or visual light transmittance. In the CITYSOLAR project, a new breakthrough concept for TPV will be developed by exploiting the combined use of emerging technologies, namely multi-junction solar modules developed from near-ultraviolet perovskite and near-infrared organic solar cells. Using advanced concepts within light management such as photonic crystals, nanophotonics and photon recycling and advanced module integration schemes, CITYSOLAR will radically change performance limits for TPV by significantly reducing losses related to light absorption and scale-up from individual solar cells to multi-junction modules. CITYSOLAR brings together world-leading European academic and industrial players, some with key intellectual property, together with two non-EU partners belonging to Mission Innovation countries specialized in the synthesis of advanced materials for hybrid and organic solar cells. The consortium will develop highly efficient and transparent solar cells and modules to increase the performance of available TPV technologies by 50%, and via innovative integration schemes present a route for its use in building integrated PV (BIPV) applications. This represents a strategic sector for Europe and an opportunity to accelerate and reduce the cost of the next generation of sustainable renewable energy technologies.
