Once we get solar cells in house paint and coat our building and appliance surfaces with solar cells, then we’ll be making progress!
Nanosolar Powersheet, a very thin film solar panel, has won the Popular Science Innovation of the Year award. The technology uses no expensive silicon and the production process is so efficient that it can make solar cells for about 30 cents per watt, or about one tenth of the cost of making traditional solar cells.
The incredibly low costs are achieved by using a printing press style machine to deposit a layer of solar absorbing “ink” on thin rolled metal sheeting. In addition to low costs, the process is also fast, making several hundred feet per minute.
Backing Nanosolar is funding from Google’s founders and the U.S. Department of Energy.
