If we're going to have graphene consumer electronics though, it's going to be based on the wafer-scale CVD manufacturing process developed in Korea and MIT.
Trust me, CVD synthesis of graphene is in the earliest of early stages. The problem is that neither group (Korea nor MIT) have figured out how to get the graphene off the nickel layer that catalyzes the reaction. There are other ways of making graphene that are much further along, such as epitaxial growth on silicon carbide.
That's actually pretty cool. By concentrating the light, they need less photovoltaic material per square foot of land used for solar. I'm curious how the efficiency of photovoltaic cells varies with the concentration of light
For a constant temperature, efficiency goes up logarithmically with light concentration. A solar cell with 1 sun on it is going to be less efficient than one with 500 suns on it assuming you have a way to cool the cells. Past a certain point the efficiency drops like a rock due to lack of cooling the cells and this reduces the voltage you can produce by about 2.3mV/C past room temp.

God that is the laziest form of protest ever. Yeah let's join a group on the service we are protesting to show how much we disagree with this new policy! If you take such exception, stop using the damned service.
