The solar efficiency problem may be solved, not by some amazing new material, but by existing and surprisingly cheap components.
Such were the findings of IBM researchers who recently achieved 9.6 percent efficiency with cells made from copper, tin, zinc, sulfur and/or selenium.
The efficiency of any solar cell refers to its photoelectric conversion rate; in other words, its ability to convert sunlight into electricity. While higher efficiency rates have been posted in the solar world (the highest so far is a 19.3 percent efficiency announced by Mitsubishi today), the IBM cell set a record for solar cells made with such low-cost and readily available materials. ...
