摘要： Photovoltaic devices conformally deposited on a nano-structured substrate having hills and valleys have corresponding hills and valleys in the device layers. We have found that disposing an insulator in the valleys of the device layers such that the top electrode of the device is insulated from the device layer valleys provides beneficial results. In particular, this insulator prevents electrical shorts that otherwise tend to occur in such devices.

摘要： Solar cells or photodetectors having one or more single-crystal shell layers conformally deposited on Ge nano-wires are provided. This approach can provide higher efficiency and/or reduced material cost compared to conventional planar approaches for multi-junction solar cells having the same thickness of active solar absorption materials. Shell layers deposited on the Ge nano-wires and including pn junctions can be grown such that they end up with single-crystal faceted tips, which can significantly improve optical collection efficiency and can improve the electron collection efficiency because of the high crystal quality.
