Descrizione del progetto
Celle solari flessibili in perovskite: efficienza, economicità e sostenibilità
Le celle solari in perovskite (PSC, perovskite solar cell) alogenata hanno raggiunto efficienze di conversione energetica di altissimo livello su scala di laboratorio, promettendo di fornire la riduzione dei costi legati all’energia che il mondo sta aspettando. Tuttavia, gli attuali metodi di lavorazione su scala laboratoriale non sono scalabili ed è sinora stato difficile sviluppare tecniche di produzione di massa per fabbricare PSC stabili in modo sicuro e, in ultima analisi, sostenibile. Il progetto HEPAFLEX, finanziato dall’UE, intende superare questa sfida combinando metodi di annealing fotonico rapido e di fabbricazione di film sottili ad ampia superficie con percorsi di chimica verde per ottenere PSC flessibili e ad alte prestazioni. I substrati flessibili supporteranno una strategia di sostituzione versatile, consentendo la realizzazione di applicazioni precedentemente inaccessibili. Congiuntamente a una strategia integrata di riciclo e riutilizzo, questo approccio incrementerà ulteriormente la sostenibilità.
Obiettivo
Achieving an efficient and sustainable photovoltaic (PV) system is a must to power the increasing energetic demands in multiple areas and contexts, in a non-detrimental way to the environment and society. Halide perovskites (HaP) have revolutionized the field due to their high photoconversion performance at the laboratory scale. Consequently, the commercialization of HaP solar cells (PSCs) is now a high-priority topic involving many research groups and companies worldwide. However, mass production methods to fabricate highly efficient, stable PSCs in a safe and sustainable manner present scientific and technological challenges, and fabrication methods at the lab scale cannot be upscaled.
To face this situation HEPAFLEX proposes to develop high-performance flexible PSCs, adaptable to multiple contexts, by redesigning the processing approach. The project will address large-area efficiency by combining rapid photonic annealing and large-area thin-film fabrication methods with green chemistry routes. This high thruput approach based on versatile cost-effective flexible substrates presents an opportunity to reduce the environmental and economic impact of the cells, ensuring the versatility of use in multiple applications, allowing for the HEPAFLEX flexible substitution strategy that will extend the effective lifetime of rigid high power supply modules >25 years reducing current photovoltaics’ cost and carbon footprint. The development of the same unique process will also enable pure flexible non-utility scale applications that maintain the highest efficiencies. These currently unfeasible applications will reduce competition between different kinds of land use. The project will ensure the safety of the technology with Pb-sequestration additive active sealants, integrated with recycling methods to reuse the materials.
HEPAFLEX will establish a sustainable PV technology based on manufacturing circularity, flexibility, versatility, replacement and recycling.
