[5] In the presence of sodium tetrachloroaurate (Na[AuCl4]), caesium carbonate is very efficient mechanism for aerobic oxidation of different kinds of alcohols into ketones and aldehydes at room temperature without additional polymeric compounds.

Caesium carbonate produces carbonylation of alcohols and carbamination[clarification needed] of amines more efficiently than some of the mechanisms that have been introduced in the past.

[citation needed] Relatively effective polymer solar cells are built by thermal annealing of caesium carbonate.

Caesium carbonate increases the energy effectiveness of the power conversion of solar cells and enhances the life times of the equipment.

It was suggested that, when Cs2O combines with Cs2O2 they produce n-type dopes that supplies additional conducting electrons to the host devices.

The n-type semiconductor produced by thermal evaporation of Cs2CO3 reacts intensively with metals like Al, and Ca in the cathode.
