One proposed strategy to boost the stability, PCEs and reliability of perovskite solar cells entails the passivation of 3D perovskite light-harvesting layers with 2D perovskites. These 2D layers ...

Researchers in China have have fabricated an aluminum contact-based TOPCon solar cell based that achieved a power conversion ...

The new study, published in the journal Science, highlights the development of a library of amidinium ligands to increase the thermal stability of passivation layers on perovskite surfaces.

“And we have confirmed that PbOx can be a good barrier and passivation layer.” Tested under standard illumination conditions, the solar cell achieved a power conversion efficiency of 21. ...

Now, a study reports a self-healing cathode with an in situ-formed passivation layer that protects metal active sites from oxidation during shutdown conditions.
