Germane

CAS: 7782-65-2
Molecular Formula: GeH4
Molecular Weight: 76.64
Product description:In the electronic industry is mainly used for metal organic chemical vapor deposition (MOCVD) technology, as an important precursor of solar cells, gas, germane is used mainly for medium containing germanium band gap of amorphous silicon germanium alloy absorption green layer, and the narrow band gap with higher content of germanium in the bottom layer of amorphous silicon germanium alloy absorbs red light. In amorphous silicon or microcrystalline silicon thin film materials, after adding germanium silicon germanium film materials can significantly adjust the material to the narrow band gap direction, so as to improve the spectral response of silicon thin film solar cells and solar cells, the light absorption efficiency of eventually making silicon thin film solar cell conversion efficiency.
