Apparently nanoelectronics has developed to the point where researchers at University of Pennsylvania working with nano-sized molecules of gold have produced a material that develops a potential (voltage) that varies according to light wavelength:

Dalsa, if you are reading this, you might take a look if you haven't already done so. There may be a method here to leapfrog the more conservative CMOS technology and produce a sensor with incredibly high resolution that is active rather than passive, conceptually simpler, and has considerably more light sensitivity than either CMOS or your current CCD materials... it may not hurt to support these guys...

Not really suitable for imaging imho.

In terms of QE, the current devices are quite good. But I guess it would be nice to have the same absolute QE at some wavelength ranges, without the need for filters.
