What does that even mean?
Even 10 times higher quantum efficiency shooting wide open on optical band targets would be physically impossible.
On top of that, 'Eliminates need for flash' is not a great title - most people who care about photography don't use flash much for direct illumination; very flat targets, indirect illumination, close-range zoomed in macro shots, and filling in a dark foreground are the exceptions. Cell phone shots look like cell phone shots in part 1) because they compensate for the tiny sensor with crappy LEDs, not even proper xenon bulbs, but mainly 2) because a 1/4" class sensor can only offer 1/3 the SNR of a cheap point & shoot 1/2.3" class sensor on a good day, for the same level of illumination: they need the flash to work, and so you get flash-based shots, which usually look horrible because of the distinctive way it lights the scene.
