Solar modules made from thin-film crystalline-silicon layers of high quality oil glass Substrates Could lower the price of photovoltaic electricity substantially. One way to create crystalline-silicon thin films oil non-silicon substrates is to use the so-called "seed layer approach", in which a thin crystalline-silicon seed layer is first created, followed by epitaxial thickening of this seed layer. In this paper, we present the first solar cell results obtained oil 10-mu m-thick monocrystalline-silicon (mono-Si) layers obtained by a seed layer approach oil transparent glass-ceramic substrates. The seed layers were made using implant-induced separation and anodic bonding. These layers were then epitaxially thickened by thermal CVD. Simple solar cell structures without integrated light trapping features showed efficiencies of up to 7.5%. Compared to polycrystalline-silicon layers made by aluminum-induced crystallization of amorphous silicon and thermal CVD, the mono-Si layers have a much higher bulk diffusion lifetime.
