This alternative solar technology could lead to low-cost, printable solar panels capable of turning nearly any surface into a power generator.
Printing solar cells may soon be as easy and inexpensive as printing a newspaper, thanks to researchers who have cleared a critical manufacturing hurdle in the development of a new class of solar devices.
Dr. Hairen Tan and his team have cleared a critical manufacturing hurdle in the development of a relatively new class of solar devices called perovskite solar cells. This alternative solar technology could lead to low-cost, printable solar panels capable of turning nearly any surface into a power generator, researchers said.
Economies of scale have greatly reduced the cost of silicon manufacturing. Perovskite solar cells can enable us to use techniques already established in the printing industry to produce solar cells at very low cost,” said Ted Sargent from University of Toronto in Canada.
“Potentially, perovskites and silicon cells can be married to improve efficiency further, but only with advances in low-temperature processes,” said Sargent. Today, virtually all commercial solar cells are made from thin slices of crystalline silicon which must be processed to a very high purity. It is an energy-intensive process, requiring temperatures higher than 1,000 degrees Celsius and large amounts of hazardous solvents.
In contrast, perovskite solar cells depend on a layer of tiny crystals – each about 1,000 times smaller than the width of a human hair – made of low-cost, light-sensitive materials. Since the perovskite raw materials can be mixed into a liquid to form a kind of ‘solar ink’, they could be printed onto glass, plastic or other materials using a simple inkjet printing process.
