Graphene: what a better use for carbon in stead of burning it. Love this.
Solution-based? So does that mean we could finally see phone cases coated with the stuff straight from the factory?
Or paint for your house?
Perhaps one could spray it on a tent or camper and be able to charge things with it so they could be used at night? ie, solar powered lights or recharge ones phone or electronics? I think it has a lot of potential.
Well now, that's impressive
Actually, the quantity of carbon used for nano applications is ridiculously small.
But yes, burning coal must stop.
Bill McKibben's "Do the Math" campaign shows that another 565 gigatons of carbon emissions take us to a CO2 level that equates a still manageable (if unpleasant) temperature rise by 2 degrees C.
Unfortunately, industry has already identified reserves of 2,795 gigatons of carbon for exploration.
In other words, until we stop massive carbon emission we are quite literally cooked.
This is good. Plenty of Carbon around. Time to find ways to use this material to our advantage.
Impressive!! As soon as the cost of solar cells goes down, I'm going to cover the roof of the house and garage with solar power cells and figure out how to use all that power.
15.6% of how much of the visible spectrum?
I wonder how durable it is? If very durable I can imagine it being applied to streets and/or sidewalks to aid in powering street lights and free Wi-Fi. Painting buildings houses and cars for free energy is another no brainer.
It would be nice to loose the silicon based cells as they inefficient and costly, I am hoping to see more details and test reports on these new cells.
can they be created for specific wave lengths ?,
can they handle high temperatures ?
Still, we are such primitives when it comes to the physics of capturing Solar, Wind, Wave, Hydro, Tidal, Geothermal, Geomagnetic, Biological, domestic, renewable, hence: perpetual energy, and so stupid about living within the confines of these. American the Wise . . . Will the Chinese Intelligentsia pool, so much wider now, so much deeper than ours, show us the way? Will their Thorium LFTR and nuclear discoveries beyond this technology reveal a new path for mankind? America, at the peak of 'Mature Capitalism" as Marx once predicted, and frozen on primitive, uninspired 'Enriched Uranium' processes, even with the end of Uranium in full sight, and locked on 22% efficient gasoline engined, rubber tired transportation, warring smaller countries for their Oil resources around the world, unable to switch to far better systems used by even China now, what does it matter to a nation of wastrels, excessive wilful over-consumers, psychopathic shoppers, even eating beyond the requirements for good health? Living in unnecessary McMansions? How will they revert to the reality of their forefathers? Seek realistic survival and truly happy lives? Even in face of their "Dumbing Down" and the moanings of the Great Corporate American Propaganda Whores ever in their ears?
At 150deg C processing may be cheaper, but it may come at the cost of less durability or less resistance to higher temperatures without some kind of treatment process developed to preserve it's properties.

You read a useful post about cheap, efficient Graphene solar cells and used that to launch a polemic against Capitalism and a love letter to unnecessary poisonous Nuclear technology ?
The Chinese are choking to death on pollution, driven by greed.
Better solar cells and better Diesel engines, coupled with the brand-new process to turn algae straight into bio-diesel, will relieve the energy bottleneck without building any more of you beloved poisonous Nuclear plants, Thorium or not.
Peroskovite is a mineral structure. You will note that this one uses Pb and some rare earth metals. Now I know that whoever owns the minerals holds the fiscal ransom, not free energy really. The energy footprint would be very costly. What is the stability to environmental erosion ie releasing the Pb from the structure. Would you like to be working in the factory with Pb and where do we put the contaminated wastes from smelting to extract the chemicals. Send them to a Mars on a rocket?
Use less energy, your fair share is much less than what you currently consume.
