Production Technology for Passivation of Polycrystalline Silicon Solar Cells

Techniques for cost-efficient operation of SiNx:H systems with a capability for hydrogen passivation in a manufacturing environment are analyzed. We conclude that SiNx:H performance may be optimized by a variety of techniques, and that the cost and productivity of the deposition tool may be the determining factors in the industry’s decision for a particular technique. PECVD constitutes the curr...

Polycrystalline silicon thin-film solar cells with plasmonic-enhanced light-trapping.

One of major approaches to cheaper solar cells is reducing the amount of semiconductor material used for their fabrication and making cells thinner. To compensate for lower light absorption such physically thin devices have to incorporate light-trapping which increases their optical thickness. Light scattering by textured surfaces is a common technique but it cannot be universally applied to al...

Silicon nanowire solar cells

Silicon nanowire-based solar cells on metal foil are described. The key benefits of such devices are discussed, followed by optical reflectance, current-voltage, and external quantum efficiency data for a cell design employing a thin amorphous silicon layer deposited on the nanowire array to form the p-n junction. A promising current density of 1.6 mA /cm2 for 1.8 cm2 cells was obtained, and a ...
