Abstract:High quality microcrystalline silicon thin film grown by Hot-Wire Chemical Vapor Deposition(HWCVD) and subsequently manufactured solar cells are presented. Intrinsic layer photoconductivity data is provided for one of the film quality measures, and the result is about 3 times higher than previously reported best record. We propose two-step microcrystalline silicon film growth mechanism, in which silicon nanoparticles are formed in the gas phase and subsequently incorporated into a solid film on glass substrates.
