<p>A thin-film semiconductor solar cell consists of a substrate, carrying a monocrystalline semiconductor layer with a direct junction, which is covered by a second monocrystalline semiconductor layer. The second has a crystal structure similar to the first, with a lattice spacing differing by =1% from the frist, but with a distance of the energy bands which is >2 kT larger. Arrangement combines the excellent radiation absorption capacity of the direct-junction semiconductor with a protection against their high rate of surface recombination of charge carriers.</p> |
