What kinda gaps in our understanding do we have that limit the reserach for this idea. I know I've seen some news or buzz about creating electricity with "green solar panals": basically using photosynthesis instead of photovoltaic cells. Maybe you can figure out a way to manage the gradient in photosynthesis by trying to see which proteins and complexes and pathways we can fiddle with to regulate it the way we want. But still, even to get to that point we need to map out and understand a lot about the reaction and system before we can begin to probe and see what we can do.
