Postpassivation of Multication Perovskite with Rubidium Butyrate

Rodrigo Szostak, Ulf Anders Hagfeldt

Many multication perovskites for highly stable and efficient solar cells benefit from rubidium iodide introduced in the precursor solution. It is well-known that Rb+ influences positively the optoelectronic and mobility properties and has a direct effect u ...

Revealing the Perovskite Film Formation Using the Gas Quenching Method by In Situ GIWAXS: Morphology, Properties, and Device Performance

Ulf Anders Hagfeldt, Sandy Sanchez Alonso, Rodrigo Szostak

The optoelectronic properties, morphology, and consequently the performance of metal halide perovskite solar cells are directly related to the crystalline phases and intermediates formed during film preparation. The gas quenching method is compatible with ...

Nanoscale mapping of chemical composition in organic-inorganic hybrid perovskite films

Ulf Anders Hagfeldt, Jorge Miguel Dias Almeida Rodrigues Soares, Rodrigo Szostak

Lead-based organic-inorganic hybrid perovskite (OIHP) solar cells can attain efficiencies over 20%. However, the impact of ion mobility and/or organic depletion, structural changes, and segregation under operating conditions urge for decisive and more accu ...

In Situ Analysis Reveals the Role of 2D Perovskite in Preventing Thermal-Induced Degradation in 2D/3D Perovskite Interfaces

Mohammad Khaja Nazeeruddin, Giulia Grancini, Albertus Adrian Sutanto, Valentin Ianis Emmanuel Queloz, Nikita Drigo, Rodrigo Szostak

Engineering 2D/3D perovskite interfaces is a common route to realizing efficient and stable perovskite solar cells. Whereas 2D perovskite’s main function in trap passivation has been identified and is confirmed here, little is known about its 2D/3D interfa ...
