Researchers in Germany are trialing a host of new processes and materials to develop interdigitated back contact solar cells. A deposition technology named 'hot-wire' chemical vapor deposition, is said to provide excellent passivation without the need for treatments such as recrystallization or hydrogenation.N-type microcrystalline silicon carbide - µc-SiC:H(n) - may exhibit excellent optoelectronic properties when it is deposited by a hot-wire chemical vapor process in silicon-based thin-film and silicon heterojunction solar cells. This costly wide-bandgap material, is thought to exhibit excellent ...Den vollständigen Artikel lesen ...
