Avantama N-31

Avantama N-31 is an advanced electron transport material that offers complete resistance to photodegradation with no activation in response to light of ultraviolet (UV) wavelengths. It comprises 7 nanometre (nm) particles of stannic oxide (SnO2) dispersed at a concentration of 2.5 WT% in a mixture of butanols. This formulation offers the highest performance when coated beneath an absorber material. However, it is suitable for generating electronic components in a range of markets via several distinct application methodologies.

If you are looking for a SnO2 formulation that provides higher performance when applied on top of the absorber, consider Avantama N-30. Otherwise, contact us directly if you have any questions.
