 This is Scientific American's sixty seconds science, I'm Christopher Intagliata. Got a minute?

Instead of installing solar paint on your roof how about just giving a house new paint job of cause you'd have to sure to use solar paint. That's what to a group of not dam researchers has created detailing the recipe at ACS Nano. The paint contains nano particles of  titanium dioxide which give whiteness to sun's green impact choker. The particles coated with semiconducting cadmium nanocrystals and mix with water in alcohol to creat a golden yellow paste. The researchers doubt the products sound believable. They brash down with conductive glass electrode and attach that to a control electrode to creat a complete circuit. When they shine light on the tiny solar cell they pump out small current, efficiency is like to electricity convertion was only about 1% much lower than the 10%-15% efficiency of conventional silicon1 cells. But the researchers say this paint is relatively2 cheep, can be made in any color and doesn't require clean room to manufacture like silicon cells just * . If they can up the efficiency of it, future time * could make electricity fence.
Thanks for the minute for Scientific American's sixty seconds science, I'm Christopher Intagliata.
