  • Patent number: 9130075
    Abstract: To provide a paste composition capable of forming a silver electrode having a high bond strength and a low contact resistance, and to provide a solar cell endowed with a high conversion efficiency and excellent reliability, the solar cell including an electrode formed using such a paste composition, a silver electrode-forming paste composition includes a silver powder, a glass component and an organic medium, and the glass component includes tellurium-loaded glass frit which is glass frit having a tellurium compound supported on surfaces thereof. This silver electrode-forming paste composition can be produced by a method which includes the steps of: preparing tellurium-loaded glass frit sintering the mixture in the temperature range of (Tm?35°) C. to (Tm+20°) C.; and dispersing the glass component and the silver powder in an organic medium using the tellurium-loaded glass frit as at least part of the glass component.

  • Publication number: 20050089934
    Abstract: The present invention provides a safe and novel stabilizing agent for enzymes; a composition containing an enzyme and the stabilizing agent; and a kit containing the stabilizing agent composition. According to the invention, deactivation or inactivation of the activity of the enzyme during storage, drying, freezing, etc. can be prevented, without raising any problem of potential infection of an enzyme with a pathogen. For purposes of the invention, the stabilizing agent for an enzyme contains a plant-derived polypeptide as an active ingredient.
