Sharp Increases Efficiency ot Thin Film Cells
Sharp Develops Mass-Production Technology for Triple-Junction Thin-Film Solar Cells
Dramatic Improvement in Conversion Efficiency, Mass Production to Begin in 2007
Sharp press release, Jan 24, 2007
Sharp Corporation has successfully developed mass-production technology for stacked triple-junction thin-film solar cells by turning a conventional two-active-layer structure (amorphous silicon plus microcrystalline silicon) into a triple-junction structure with amorphous silicon (two active layers) and microcrystalline silicon (single active layer). This new architecture boosts cell conversion efficiency from 11% to 13% and module conversion efficiency from 8.6% to 10%. Mass production is slated to begin in May 2007 at Sharp’s Katsuragi Plant in Nara Prefecture. ...
