We regularly see stories about higher efficiency cells. I know it must be hard to accomplish but I sure hope at least one becomes reality.

Yeah, like everything the challenge is to get from the Lab to production. Perovskite solar cells, another type of solar cells that show great theoretical promise, have issues with long-term stability. Solar cells need to survive in tough conditions for many years to be useful. Here I would also wonder about the relative scarcity of gallium being a limiting factor.
