New Material Can Absorb Infrared, Increase Solar Efficiency
ecogeek.org — Semiconductor solar cells absorb sunlight from the visible spectrum, ignoring ultraviolet and infrared rays, which limits how much energy a solar cell can create from sunlight. But a new material made by researchers in Spain throws titanium and vanadium into the mix so it can utilize infrared and potentially boost efficiency of solar cells.

The energy of the sun was stored, converted, and utilized directly on a planet-wide scale. All Earth turned off its burning coal, its fissioning uranium, and flipped the switch that connected all of it to a small station, one mile in diameter, circling the Earth at half the distance of the Moon. All Earth ran by invisible beams of sunpower." - 'The Last Question' by Isaac Asimov
His idea that it would take a computer with "miles and miles of face" to solve the problem is outdated - and hopefully his timing is off by a few decades in our favor. But I certainly hope his vision becomes reality.
http://www.multivax.com/last_question.html - Felix90, on 08/06/2008, -0/+0The important question here is "how much does it cost?"
- PatNolan, on 08/06/2008, -0/+1Less than the Manhatten Project and more than a cotton gin. But really, who cares about the cost in the research phase. Mass Production will drive the cost down.
- Felix90, on 08/08/2008, -0/+1But if the materials used are too rare, mass production won't be possible.
