Researchers at Stanford have developed a technique that can rapidly and sequentially separate multiple sets of III-V solar cell thin films grown as a stack on one III-V wafer.
Electronic devices made from single crystal thin films attached to inexpensive support substrates offer reduced material costs compared to wafer-based devices; however, scalable and inexpensive processes for producing these single crystal film structures have remained elusive.
Stanford researchers have patented a low cost, textured crystalline silicon (c-Si) photovoltaic film fabricated via scalable, ion beam assisted deposition (IBAD) on display glass.
