Recent progress on microcrystalline solar cells

The most important features of microcrystalline silicon (/spl mu/c-Si:H) and microcrystalline silicon based p-i-n solar cells (specially those deposited by VHF-glow discharge) are reviewed. Since such material has been recognized to be a photovoltaically active material, stabilized cell efficiencies have steadily risen and have now reached 12% in the so called "micromorph" (microcrystalline/amorphous) tandem cell configuration.
