CIGS technology — for copper, indium, gallium and selenide — is a thin - film approach that will initially be able to convert at least 15 percent of the solar energy it receives into electricity, says Supratik Guha, a senior manager at IBM's T. J. Watson Research Center in Yorktown Heights, N.Y..
A host of companies, including HelioVolt, Nanosolar and others, are using
CIGS technology in an attempt to cut the cost of producing photovoltaic cells.
A better bet than Solyndra with
CIGS technology may not be cylinders but rather more flexible arrangements, like a solar carpet being developed by Solopower with another DoE loan guarantee or PV shingles, such as those developed by Dow.
