This is just bifacial and it’s been on the market for a little bit already.

…harvests reflected sunlight hitting the back of the device, offering an unconventional route to producing higher energy yields for less space and cost.

Less cost seems probable. Less space really does not. Gonna probably need some mirrors to reflect onto that back surface, and it’s still going to require the same amount of incident area of solar radiation.

Mirrors are pretty cheap, though. So seems like a win.
