Semetransparent Perovskite-Graphene Solar Cell 12% $0.05 by watt

This might hit hard in the Solar cell field.

They made a semitransparent perovskite solar cells with graphene electrodes, this double the efficiency reached before by semetransparent solar cells, it also reduce the cost by half.

May be this the first graphene base product to be sold at large scale?

It can absorb light from both sides, it will be cheap to produce due the materials used and by the reason it can be manufacture in rolls with vapor deposition.

Taking into account that is semetransparent, flexible and light weight (plus cheap), it will be no hard to find it uses.

Something that I am not sure how to understand is this:

"The power conversion efficiencies (PCEs) of this novel invention are around 12% when they are illuminated from Fluorine-doped Tin Oxide bottom electrodes (FTO) or the graphene top electrodes, compared with 7% of conventional semitransparent solar cells. "

When is illuminated from flourine??

The production cost might be low as $0.05 by watt, which give us $50 by kw, and $5000 by megawatt (production cost, once the factories are ready for this).

Flouride is a dope, when an electron is kicked there needs to be something to fill the hole momentarily until the circuit is complete, At least thats the way i understand it depending on whether its a p or n type conducter you need a carrier to fill the holes, when florine gains a electron it becomes a negative carrier and fills a hole left by a kicked electron until that electron completes circle, tin being polyvalent cation can accomidate the loss of a floride and awaits its return. It has ti do something with the fact that if the holes don't fill current falls and the layers can degrade. My understanding is 30 years old so .......

Its sort of like pipe dope, you use pipe dope between two milled ends of the pipe because although the pipe will pass liquid, when its not flowing without the dope in the threads, the pipe will leak. Not only is this messy, but it causes erosion of the threads and will make the problem worse. So being a dope in a leaky world is a good thing.
