Periodic Reporting for period 2 - CREATE (Crafting Complex Hybrid Materials for Sustainable Energy Conversion)
Période du rapport: 2021-07-01 au 2022-12-31
The overall goal of CREATE and the PDLD method is to achieve maximum versatility for hybrid materials screening and discovery, and maximum growth control to tailor film properties and study the role each component has in the overall optoelectronic properties of the films. This will enable new and optimised materials for solar cells and novel optoelectronic devices.
1. Fabrication of CsSnI3 with stable black orthorhombic phase and no Sn oxidation demonstrated with pulsed laser deposition (PLD).
2. First time demonstration of PLD of double perovskite Cs2AgBiBr6. PLD has demonstrated to be an unique method that allows stoichiometric transfer of the 4 elements from a Cs2AgBiBr6 target to a Cs2AgBiBr6 thin film.
3. PLD not only allowed the deposition of complex inorganic halide perovskites from a single source, but also of hybrid organic inorganic perovskite films with up to two different organic cations. This opens up the path to simplified process for solar cells and even future tandem devices.
Expected results until the end of the project include the development of the PDLD method, which will be a unique system worldwide. Both, PLD and PDLD, offer solutions beyond state of art on deposition methods of halide perovskites. PLD will offer scalability and simplified processing, and PDLD will offer full versatility in terms of composition and structural motifs.
