A group of researchers has discovered a way to potentially use graphene for photo detectors in future products such as digital cameras or night vision goggles.
Typically, graphene has rather terrible light-sensing capabilities as it is just 3 percent efficient. However, graphene is apparently good enough to become a photo detector material when it is covered gold electrodes, as well nano-scale crystals, commonly referred to as quantum dots. The scientists experimented with different mixes of the material and finally ended up with a detectivity of 7×10^13 Jones. It is not exactly record breaking for photo detectors overall, as the best detectors today reach more than 1x10^14 Jones at room temperature.
However, the results were still good enough to predict that graphene will also make its way into photo detectors and surface in mass market applications. The research team at the Institut de Ciencies Fotoniques in Barcelona, Spain, said it is now focusing on increasing the size of its detector to "real-world application" sizes.
Graphene's the bees knees. We get it. Now show us some products based on it.

Proofread this crap....
I was just going to post something along these lines.
A first grader can write better than these so-called "professionals", and I use that word lightly!
OMG, one atom thick graphic display!
It might still be thinner than contemporary photo sensors, despite the gold electrodes and the nano crystals increasing it's thickness compared to a single layer of graphene.
Isn't graphene made from pencil lead using adhesive tape as the only tool? So, for a factory, you would just need big pencils and huge rolls of tape. );
Pencil lead is graphite.
I know. There was a wonderful story about isolating graphene from graphite using only Scotch tape. It was part of the research that won the Nobel prize in Physics in 2010. http://www.nobelprize.org/nobel_prizes/physics/laureates/2010/speedread.html
It appears that you smear some graphite on a piece of Scotch tape. Put another piece of tape over it and separate them. This pulls layers apart.
Repeat until all the pencil lead stays on one or the other piece of tape. You now have fragments of single-plane arrangements of carbon atoms, or graphene.
I was joking about scaling that process up to industrial levels, using immense pencils and immense rolls of tape.

Huh, learn something new every day. I don't remember hearing about that.
In most cases theres enough room for .5m fatter (lol dont know the word). So yeah even 5cm is over-everything for normal needs
