  • Publication number: 20120177531
    Abstract: A powder composition and a sintered body thereof are presented. The powder is a martensitic stainless steel powder for powder injection molding without deformation problems during sintering. The powder composition includes 0.80-1.40 weight percent (wt %) of carbon (C), less than 1.0 wt % of silicon (Si), less than 1.0 wt % of manganese (Mn), 15.0-18.0 wt % of chromium (Cr), 0.10-2.50 wt % of titanium (Ti), and the remainder iron (Fe). The powder can be sintered with a sintering temperature varying within 50° C. and can reach a high density without distortion, and thereby a good dimensional stability is obtained.

  • Publication number: 20120103413
    Abstract: A thin-film solar cell includes a body and a polymer layer. The body includes a first electrode layer, a photoelectric conversion layer, and a second electrode layer, and the polymer layer includes a hardening material and an interface material. The photoelectric conversion layer is disposed between the first electrode layer and the second electrode layer, and the polymer layer surrounds the photoelectric conversion layer, in which the interface material is used for bonding to the hardening material and the photoelectric conversion layer respectively. Therefore, the thin-film solar cell may reduce the Staebler-Wronski Effect generated by the photoelectric conversion layer in the photoelectric conversion procedure. Accordingly, the photoelectric conversion efficiency is improved.
