kesterite

Previous work in Japan had shown that such "kesterite" cells could achieve efficiencies of nearly 7 percent-not enough for deployment in the field, where lab efficiencies are usually cut at least in half-but promising.

But the IBM team deposited most of its material as a mixture of particles and solution, like printing with kesterite "ink" made from copper and tin in solution with particles of zinc.

And "it's not obvious that this is limited to low efficiency," meaning there is more room to improve. no plans to manufacture such kesterite cells, preferring to license the technology.

The ultimate benefit of both of these technologies may be flexibility as well as cost-both the silicon microwires and kesterite cells could conceivably be made into a variety of flexible devices, including some woven into fabrics, Mitzi says.

By varying the ratio of sulfur and selenium, Mitzi and his colleagues were able to boost the overall efficiency of the kesterite solar cell by 40 percent.
