Neither the linked article nor the abstract explain how this actually works.

Yeah very sciency, even has the word Scientists in the bb headline, but no description of any actual science in the abstract or summaries. I am not going to go on a wild science chase.
This breakthrough might be popular in places like Rjukan in Norway which sees little winter sun. They use industrial-size Heliostats (@PsiPhiGrrrl). So the electricity this new solar cell accumulates could be used for town lighting or at least to power a tanning salon on every corner.
This tells it even better:

As I understand it, it works by harvesting the difference in energy potential between light and dark areas of a semiconductor. This difference creates flow of electrons from one area to the other and this is what is being harvested. That is why this method works best when the harvesting surface is half in light and half in shadow.

Those aren’t hard to solve. Stick it behind an LCD array and aim a camera at it (or embed a detector) to control the LCD.
