SOLVENT-FREE SOLID-STATE SYNTHESIZED PEROVSKITES

28.01.2022

Nanoxo introduces novel solvent-free solid-state synthesized perovskites with band gaps between 1.5 to 2.9: β-MAPbI3, α-FAPbI3, γ-CsPbI3, GuaPbI3,  α-MAPbBr3,  α-FAPbBr3, and γ-CsPbBr3.
The solvent-free solid-state approach ensures repeatability and scalability of the manufacturing process while providing remarkably high phase purity products. The reaction of dry powders also eliminates the formation of solvent adducts, arising through their coordination to perovskites, resulting in crystal lattice defects.

Solvent-free solid-state synthesis method ensured the remarkable improvement of perovskite solar cells parameters. Devices manufactured with inks made from dry perovskites exhibited reduced I-V hysteretic behavior, increased open-circuit voltage values (VOC), and considerably better thermal stability due to a higher degree of crystallinity. Moreover, the utilization of the solvent-free synthesis method guarantees complete control over reaction stoichiometry, thereby preventing the presence of starting materials.
