POPSThin Film Photovoltaics Thin film photovoltaics are an interesting develpment. Fuelled by a worldwide shortage of silicon (caused by a huge growth in demand for solar energy) thin film solar has risen in popularity. While less efficient (now) than traditional solar panels, thin film is cheaper to produce.

POPSSilicon Valley? How about Solar Valley! Just another indication of how fast the momentum behind alternative energy is picking up steam. If the government extends tax credits for wind and solar, i think this industry is in for a very long bull market.

POPSSolar Cells That Work All Day Once the carbon-nanotube towers are complete, they are coated with cadmium-telluride and cadmium-sulfide semiconductors, which do the work of electron generation. Finally, a thin coating of indium tin oxide is deposited to serve as an electrode. In the finished cells, as with some other nanosolar approaches, the nanotubes serve both as a scaffold for the photovoltaic material and also as a conductor to help move electrons to the electrodes. In Ready's technology, each square centimeter of the finished solar cell contains 40,000 towers, and each tower consists of millions of vertically aligned carbon nanotubes.
