Two very different energy-harnessing technologies, the silicon solar cell and the steam engine, may someday be ranked as having equal significance.

Today the powerful legacy of James Watt's steam engine, a machine that converted the heat of burning wood or coal into the mechanical motion that drove factories, locomotives, and boats, is well known. Yet the technology's heyday has passed, its functions as a mobile power source having been overtaken by internal combustion ...

The Potential of Thin-film Crystalline Silicon Solar Cells.
Semiconductor International ; By Koen Snoeckx, Guy Beaucarne, Filip Duerinckx, Ivan Gordon and Jef Poortmans, IMEC, Leuven, Belgium, www.imec.be If the efficiency and cost targets can be met, thin-film crystalline siliconsolar cells have the potential to become a solid alternative to the bulk multi-crystalline silicon solar
Silicon solar cells: Physical metallurgy principles
JOM ; This article reviews the physical metallurgy aspects of silicon solar cells. The production of silicon solar cells relies on principles of thermochemical extractive metallurgy, phase equilibria, solidification, and kinetics. The issues related to these processes and their impact on solar cell
ENERGY Titania Nanotubes Promise Better Solar Cells.
Nanoparticle News ; A new generation of solar cells made from titania nanotubes doped with a dye, may be the answer to making solar electricity production cost-effective, according to Craig Grimes and his research team at Penn State University. Grimes says, solar cell technology has not changed very much over time and
Thinner is better in solar cells: thin films and slimmed-down cell structures look like the next big step in shrinking the cost per watt of solar power.(SEMICONDUCTOR MFG: Special section)
Machine Design ; Solar cells today can't generate electricity as cheaply as fossil fuel-fired generators--but stay tuned. New developments in cell fabrication and manufacturing techniques may start to close the cost gap. Today, solar power accounts for less than 1% of worldwide electricity generation, according to
