Two-step MAPbI3 deposition by Low-Vacuum Proximity-Space-Effusion for high-efficiency inverted semitransparent perovskite solar cells Emanuele Smecca, Vitantonio Valenzano, Salvatore Valastro, Ioannis Deretzis, Giovanni Mannino, Graziella Malandrino, Gianluca Accorsi, Silvia Colella, Aurora Rizzo, Antonino La Magna, Andrea Listorti and Alessandra Alberti Abstract Halide perovskite solar cells can combine high photoconversion efficiency with high transmittance.

Highlights Insight into the reactivity of perovskite inks under different experimental conditions Addition of methylamine to formamidinium gives trans/cis N-methylformamidinium Cs+ significantly stabilizes the precursor solution by slowing down the reaction NMR is a powerful tool to predict solution modifications prior to device fabrication Summary Over the past 10 years, organometal halide perovskites have revolutionized the field of optoelectronics, particularly of emerging photovoltaic...
