Avantama N-31

Avantama N-31 and Avantama N-30 are advanced high-performance electron transport material formulations consisting of finely tailored stannic oxide (SnO2) nanoparticles dispersed in a mixture of 1- and 2-butanol. While primarily serving as electron transport materials in thin-film solar cells, they also find suitability across a variety of functions in printed electronics applications that demand extended photodegradation stability such as photodetectors, organic light emitting diodes (OLEDs) or sensors. Avantama N-30 and N-31 are compatible with organic photoactive materials as well as Perovskite absorbers in cutting-edge photovoltaic applications.
The butanol-based SnO2 formulations are designed to be conveniently applied using low-temperature coating techniques such as spin-coating, doctor-blading or slot-die.

The difference of Avantama N-30 and N-31 lies in its surface chemistry and therefore band energy alignment. Please contact us for further information and recommendations which product is best suited for your application.
