Hybrid perovskite solar cells (PSCs) are one of the most promising technologies for new-generation photovoltaics due to outstanding semiconductor properties and low-cost solution processing methods for the fabrication. Indeed, PSCs dominated the PV scientific research in the last decade, by developing efficient and stable devices, produced by employing scalable and low-cost printing techniques, easily embedded in roll2roll or sheet2sheet production lines. Moreover, perovskite (PSK) PV has been recently demonstrate to work in synergy with the silicon solar cells by achieving astonishing power conversion efficiency (PCE) above 33% on small area perovskite/silicon (PSK/Si) tandem solar cells, making such new PV technology appealing for the market.[1] However, PSK/Si tandem technology still requires to demonstrate the transfer from lab to fab, pushing the scientific community in finding brilliant solutions for …
