This is a far stretch but it may also explain why we have heard nothing from Dr. Jabbour. Reverse engineering a film from a solar cell would not be out of the question for this man. His solar cells will be film and the screen for the displays are film. He engineers his film instead of producing a current from light he reverse engineers the film to produce a specific light from a current. It's a challenge the guy would be all over, like white on rice!
Hope something gives soon.
