Apparently, existing solar cells that use silicon semiconductors cost around "$2.30 to generate one watt of electricity," whereas this group's solution costs just ten cents per watt. Better yet, plans are already in motion to increase efficiency up to 15-percent, after which we could see these things hitting the marketplace at large "by 2012."
That cost per watt is misleading.
Once a Solar Panel is made, installed, and start producing current there is a life span of the Solar Cell that begins to account for the production of electric 'wealth'.
If the Solar Cell cost 800 dollars, then, at some point in time the electric output of the Solar Panel will reach 800 dollars worth of electricity. I've done the math myself and came up with 90 months. The guarantee for a Solar Panel is 25 years.
In other words: the Solar Panel pays for itself in 90 months and then produces free electricity from that point on.
There are 300 months in 25 years.
210 months worth of 'profit' for the investment of one Solar Panel.
How can that equate to cost per watt? A solar panel is a wealth generator. It makes money. It makes value. It makes wealth. The cost of a Solar Panel is an investment. The cost of a Solar Panel is not a cost.
The cost per watt is a price per watt of 'output' for the Solar Panel. The "output" is guaranteed for 25 years.
