Abstract:
We report progress made at the National Renewable Energy Laboratory (NREL) on crystal silicon solar cells fabricated by epitaxially thickening thin silicon seed layers on glass using hot-wire chemical vapor deposition. Four micron thick devices grown on single-crystal silicon layer transfer seeds on glass achieved open circuit voltages (Voc) over 600 mV and efficiencies over 10%. Other devices were grown on laser crystallized mixed phase solidification (MPS) seeds on glass and e-beam crystallized (EBC) a-Si on SiC coated glass seeds. We discuss the material quality of the various devices on seeds and summarize the prospects for the seed and epitaxy PV approach
