Projektbeschreibung
Solarfenster auf ganz neuem Niveau
Transparente Solarzellen in Form von Fenstern sind bereits Realität. Jedoch sind sie bei der Umwandlung von Sonnenlicht in Strom bisher nicht ausreichend effektiv. Das EU-finanzierte Projekt CITYSOLAR will das nun ändern, indem es zwei Photovoltaiktechnologien in einer Tandembauform vereint. Im Einzelnen wird CITYSOLAR Mehrfachsolarzellen entwickeln, die hinsichtlich der Absorption verschiedener Wellenlängen des Sonnenlichts optimiert sind. Dazu werden neue Perowskit-Solarzellen, die eine große Energiebandlücke aufweisen, mit organischen Solarzellen kombiniert, die frei von Fullerenen sind und eine geringe Energiebandlücke haben. Somit wird hochtransparenten Solarzellen der Weg bereitet, die infrarotes und ultraviolettes, jedoch kein sichtbares Licht absorbieren. Der Umwandlungswirkungsgrad wird bei mehr als 15 % liegen.
Ziel
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.
