摘要：
A reusable substrate and method for forming single crystal silicon solar cells are described. A method of forming a photovoltaic cell includes forming an intermediate layer on a monocrystalline silicon substrate, forming a monocrystalline silicon layer on the intermediate layer, and forming electrical features in the monocrystalline silicon layer. The method further includes forming openings in the monocrystalline silicon layer, and detaching the monocrystalline silicon layer from the substrate by selectively etching the intermediate layer through the openings.
