Title: Material and Device Analysis for Efficiency Improvement in Epitaxial Crystalline Solar Cells: Cooperative Research and Development Final Report, CRADA Number CRD-11-433

Crystal Solar has a novel approach for producing low-cost, monocrystalline silicon wafers that are capable of yielding high-efficiency solar cells. The approach involves epitaxial growth of the substrate and a proprietary lift-off technology. Crystal Solar will send selected wafers and cells to NREL for characterization and analyses. NREL will apply a variety of techniques to help identify mechanism(s) that limit the cell efficiency and suggest suitable approaches for mitigation.
