From the summary, it says the material had "high gain photoconductivity." I don't know if that means relative to current CMOS and CCD sensors, but there are always "like to haves" with any technology.
Right now, I'd like to have something that shoots at ISO3200 and above with very low noise, something that is currently difficult without software noise reduction algorithms or only on very expensive cameras (e.g., the Nikon D3 shoots at up to ISO 25,600). If this new material were better in the sensitivity/noise realm, and not just cheaper, it would be a gamechanger.
