Twin Creeks Technologies—a startup that has been operating in secret until today—has developed a way to make thin wafers of crystalline silicon that it says could cut the cost of making silicon solar cells in half. It has demonstrated the technology in a small, 25-megawatt-per-year solar-cell factory it built in Senatobia, Mississippi. Siva Sivaram, the CEO of Twin Creeks, says the company’s technology both reduces the amount of silicon needed and the cost of the manufacturing equipment. He claims the company can produce solar cells for about 40 cents per watt, which compares to roughly 80 cents for the cheapest solar cells now. Twin Creeks has raised $93 million in venture capital, plus loans from the state of Mississippi and other sources that it used to build its solar factory.
