One of the challenges to the future of rooftop photovoltaic technology progress is the development of Crystalline Silicon. Solar cells are made from wafers which in turn are fashioned from molten silicon ingots. Silicon is wasted in the process of slicing these ingots into wafers. This waste is called called “kerf loss.” To bring down the cost of photovoltaic cells, researchers are seeking to cut down on this silicon waste to make the manufacturing process more efficient.
The SunShot Initiative, a project of The U.S. Department of Energy (DOE) Solar Energy Technologies Office, is dedicated to making solar energy cost-competitive with other forms of energy by 2020. To this end, the SunShot Initiative funds research into promising technology from proof-of-concept to pilot programs and on into market-ready, mass production products. In addition to Chrystalline Silicon, the Initiative is also funding research into Thin-Film, Multijunction, Organic, Dye-Sensitized photovoltaic technologies.
One of the Arizona State University’s Solar Power Lab current projects, “Kerfless Crystalline-Silicon PV: Gas to Modules” is a process which creates ultra-thin silicon wafers by using vapor to deposit silicon onto reusable surfaces. This method uses significantly less silicon than current manufacturing techniques making it virtually “kerf-less.” It saves money for the company by using less silicon in the wafers as well as wasting less silicon. These savings can then be passed along to you in lower-cost photovoltaic cells and overall costs of solar panels. Arizona State University’s other Crystalline Silicon research goals include ultra-thin silicon solar cells with efficiencies of 29%.
