Description du projet
Du photovoltaïque organique pour des bâtiments écologiques
Les systèmes BAPV (building applied photovoltaic) exploitent des panneaux solaires installés sur les structures des bâtiments, comme les toits ou les façades, afin de produire de l’électricité. Le projet BOOSTER, financé par l’UE, a l’intention d’utiliser des films photovoltaïques organiques souples (OPV pour flexible organic photovoltaic), ces derniers étant considérés particulièrement adaptés aux applications BAPV. Les modules OPV se caractérisent par un faible temps de retour énergétique et utilisent des ressources disponibles en abondance, facilement accessibles et non toxiques. Le projet fera passer la technologie OPV au TRL 7 en améliorant l’efficacité et la durée de vie des modules, tout en optimisant les coûts de production. Les chercheurs procéderont à la démonstration d’un module «prêt à appliquer» et d’un produit intégré à un matériau textile dans le but de valider ce principe de manière convaincante.
Objectif
In the context of increasing energy demand, thin film PV technologies contribute in reducing CO2 emission. Current PV technologies are suffering from several issues: 1 – the outsourcing of PV modules outside Europe, 2 – the large distance between consumption points and generating power plants and 3 – the use of agricultural fields by solar power plant. In this context, building applied photovoltaic (BAPV) approach can face these issues by bringing functionalization to facades or roofs with a small constraint on the building. BOOSTER project targets at deploying the OPV technology to the BAPV market. OPV is a technology that addresses the problematic of world energy production with an eco-responsible approach. Manufacturing OPV modules via printing techniques features a low energy-payback-time and uses resources that are abundant, easily accessible and non toxic. Additionally, OPV demonstrates properties (flexibility, lightweight) that make it easily suitable for BAPV. Recently, technology benefited from a rapid progress of performances with development of advanced materials. The project BOOSTER aims at bringing the OPV technology to a TRL 7 by increasing efficiency, lifetime together with optimizing costs and lowering carbon footprint. Two demonstrators will be installed to illustrated BAPV concepts: a “ready to stick module” and a textile integrated product. BOOSTER will provide an efficient multi-layer OPV architecture demonstrating efficiency up to 15 %. Advanced multifunctional barrier films will be manufactured to increase the lifetime to 35 years. With a large-scale production approach, efforts will be placed on scaling up all the materials and optimization of the R2R manufacturing line to coat all the layers with minimization of performance loss while targeting drastic cost reduction. BOOSTER BAPV products will be integrated in two different locations (FAU in Germany, ENI in Italy), where real-life efficiency will be studied during last year of the project.
