Perovskite Solar Cell Materials: Introduction, Structure, Composition, Doping, Defects -Edit RMW-UvA

#perovskite #solar #photovoltaics #nanomaterials #solarcell #education #photochemistry
This is a recorded Zoom lecture at the MSc level for chemistry students that are interested in Nanotechnology and Supramolecular Chemistry. Nanotechnology and Nanomaterials 9.
Photoactive Nanomaterials. There are ~10 video's in this course

This lecture introduces the Perovskites as a solar cell materials. Their structure and components are discussed. Than focus is on doping with zinc (II) ions as well as other lattice strain releasing small ions.

04-10-2023: Thanks to Federica Arbore for asking a question!! (at ~14:30).

Learning objectives:
Perovskites have the steepest rise of efficiency vs time of all solar cell materials.
It is expected that they will surpass silicon in the coming years.
Pb(II) is related to all high efficiency compositions, but Sn(II) can also be used (as B), next to methylammonium, formamidinium, ceasium and rubidium as monovalent cations (as A). Halogens form the anions (X), and strongly influence the bandgap. Iodides are most strongly colored ABX3 materials.
Doping of perovskites can strongly influence their properties.
Methylammonium is the weakest component and should be avoided.



NEW ADDITION: 15-05-2024
It can be noted that in our most recent work we show that
WE DO NEED METHYL AMMONIUM
to get good films. Its evaporation during spin-coating and annealing plays a role. Without MA we could not get nice films!!

"Indeed, it is widely accepted in the research society that MA-based perovskites are less stable concerning humidity and thermal stress".
