Product portfolio

Four families of interfacial materials

MoleculaX offers a portfolio of proprietary interfacial technologies for high-performance, reliable perovskite solar cells, positioning us among the few providers offering comprehensive material solutions for scalable and cost-effective manufacturing.

Inorganic Nanoparticles

Solution-processable metal oxides that enhance device stability while reducing manufacturing costs.

Passivation Contacts

A reagent that addresses the volatility and migration issues of traditional small cations, enhancing perovskite stability.

Ion Blocking Contacts

A design that combines physical blocking and electrostatic ion confinement to suppress ion migration, enabling enhanced long-term stability.

Polymeric Transport Materials

A series of polymers designed to replace conventional SAMs and small molecules, delivering enhanced device stability.
