  • Patent number: 10134930
    Abstract: The present invention provides a 3-dimensional P-N junction solar cell composed of a base board coated with a back plate on the upper face of the same; a P type semiconductor thin film formed on the top side of the back plate which has a 3-dimensional porous structure and is composed of P type semiconductor crystal grains; a N type buffer layer formed on the surface of the crystal grains of the said P type semiconductor thin film with playing a role of coating the thin film; and a transparent electrode formed on the surface of the crystal grains of the P type semiconductor thin film on which the N type buffer layer is formed. The solar cell of the present invention is a P-N junction solar cell including a 3-dimensional photo catalytic thin film, which can provide an improved photoelectric conversion efficiency, compared with the conventional P-N junction solar cell, owing to the formation of the N-type buffer layer on the surface of the crystal grains of the 3-dimensional P type semiconductor thin film.

  • Publication number: 20140377737
    Abstract: The present invention provides a method of culturing pancreatic islet cells using a cationized atelocollagen prepared by ionization of high purity atelocollagen, a method of preparing a carrier for pancreatic islet cell transplantation using a cationized atelocollagen, and an artificial pancreas prepared using the same. According to the present invention, it is possible to increase the viability and/or glucose-dependent insulin secretion of pancreatic islet cells during culture of the cells by the use of a cationized atelocollagen or crosslinked atelocollagen scaffold obtained by ionization of high purity atelocollagen. In addition, it is possible to increase the viability and glucose-dependent insulin secretion of cultured and transplanted pancreatic islet cells by the use of a highly stable carrier for pancreatic islet cell transplantation that comprises cationized atelocollagen and alginate.

  • Patent number: 8748579
    Abstract: Disclosed herein are a collagen-based matrix for use as a restorative material and a method for the preparation thereof. An atelocollagen dispersion is spread at a predetermined thickness over a plate and freeze-dried to form a porous collagen membrane. An atelocollagen dispersion is separately spread over a plate and pressurized to form a dense collagen membrane. This is overlaid with the porous collagen membrane and immersed in an EDS solution in ethanol to crosslink the two membranes with each other. From the bilayer structure thus constructed, EDS is removed, followed by lyophilization and cutting into an appropriate size.
