ibm solar cells IBM Claims Breakthrough in Solar Tech

Researchers at IBM have claimed to have found a new path to solar power, one that will make solar panels a lot more cheaper. The cheaper part is achieved by the use of “Earth abundant” elements, the use of which will be comparatively more cost effective than the Copper, Indium, Gallium, and Selenium that GIGS thin film cells use.

These abundant elements in question are copper, tin, zinc, sulfur and selenium. With the sunlight absorbing layer made of these elements than those listed earlier, the cost of the solar panels can be brought down. It isn’t just the cost these new panels are supposed to save, the conversion efficiency for such solar cells is at 9.6%, a 40 percent increase over previous such attempts, and there is always a possibility to boost efficiency further.

IBM says that it has no plan to step into the solar tech manufacturing arena, but it would be willing to partner with solar cell manufacturers.
