Materials technology developed at IBM's research labs is inching closer to commercial solar panels.
Japanese manufacturer Solar Frontier said yesterday it has signed a deal to develop thin-film solar cells originally designed by IBM.
IBM researchers last year showed they were able to improve the efficiency of solar cells made from a combination of copper, zinc, tin, sulfur and selenium (CZTS), hitting an efficiency mark of 9.6 percent in the lab. Although they are generally less efficient than silicon, thin-film solar cells promise to be cheaper because less material is needed.
Solar cells made from other thin-film materials … Read more
