Sigurd Wagner is seeking to introduce fundamentally new electronic materials. He has been working in three areas: (i) new materials for solar cells; (ii) hydrogenated amorphous silicon; and (iii) flexible, conformably shaped and stretchable large-area displays, electrotextiles, and electronic skin. At present he is developing an environmental barrier layer for organic electronics, and is collaborating with colleagues on the integration of flexible electronics into complete systems. Beginning with work at Bell Laboratories, where he co-invented the CuInSe2 (CIS), CuInS2, and Cu2CdSnS4 solar cells, among others, he has had a long-standing interest in solar energy conversion.
