The key to this new technology is less raw material and less waste during manufacturing. The process is "a continuous, automated manufacturing process for solar panels using glass coating with a cadmium telluride thin film instead of the standard high-cost crystalline silicon. Because the process produces high efficiency devices (ranging from 11 percent to 13 percent) at a very high rate and yield, it can be done much more cheaply than with existing technologies. The cost to the consumer could be as low as $2 per watt, about half the current cost of solar panels, and competitive with cost of power from the electrical grid in many parts of the world. In addition, this solar technology need not be tied to a grid, so it can be affordably installed and operated in nearly any location said the university in a press release. The technology has been developed by Professor W.S. Sampath.
