This lecture introduces the tandem solar cell materials, perovskite on silicon cells. Their structure and components are discussed.

This lecture is based on a "Perspective" published in the journal "Photochemical and Photobiological Sciences", of the Nature Publishing Group.

Marchant, C., Williams, R.M. Perovskite/silicon tandem solar cells–compositions for improved stability and power conversion efficiency. Photochem Photobiol Sci (2023).

The literature Thesis of Charles Marchant was used as the starting point for this Perspective. Charles has now obtained his MSc and is in Australia.

16-11-2023 addition:
LONGi now reported 33.9% PCE!! LONGi is a big silicon solar module producer.

Learning objectives:
Perovskites on silicon tandem cells have shown a sky-rocketing rise of efficiency in recent years.
It is expected that they will increase to 34 or 35% PCE soon.

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.
But it now seems it is needed for good spin-coating!!

QUIZ 1: Which pop-song title can be linked to the content of this talk?
(If you can't beat them join them!!)

QUIZ 2: Is there new information on the composition of recent tandem record materials?
(no papers yet linked to 33+ % PCE devices).

QUIZ 3: How much current (mA/cm^2) would a perovskite on silicon tandem cell give if it would reach the Shockley Queisser limit for tandems? (if it gives 2.3 V).
