Effect of germanium fraction on the effective minority carrier lifetime in thin film amorphous-Si/crystalline-Si1xGex/crystalline-Si heterojunction solar cells
The effect of germanium fraction on the effective minority carrier lifetime (τeff) for epitaxial Si1-xGex layers is extracted using measurements on amorphous(a) Si(n+)/crystalline(c)-Si1-xGex(p)/crystalline(c)-Si(p+) heterojunction solar cells with x = 0.25, 0.41 and 0.56. The τeff extracted for Si0...
