Scientists report progress toward cheaper solar panel
Solar panels generate electricity by absorbing sunlight, but that is only half the battle.

"In theory, this type of ceramic could realize efficiency above 50 percent, though a lot of work remains to be done, the authors said."
500 Watts per square meter, that ups the disruptive quality of the solar PV industry against the intrinsic players of the fossil fuel industry. Standard sized panels today are around 230 watts for about 15 square feet of panel area. At the 50% efficiency mark, you're looking at right at 700 watts per panel.
"The authors say their new ceramic also would have an edge over "thin-film" solar panels, which tend to contain materials that are rare, toxic or both. The new material contains potassium, niobium, barium and nickel, which are relatively abundant and environmentally benign."
Interesting, those who pundit the fossil fuel industry almost always point to the toxic environment and waste creating solar PV panels required for manufacture. What happens to that argument now? I wonder if these guys can come up with a good ceramic storage system for solar PV?
