  • Publication number: 20200168753
    Abstract: The present invention relates to an encapsulant capable of reducing potential-induced degradation (PID). The encapsulant is used to seal a solar cell to form a photovoltaic module, in which silica gel is dispersed in the encapsulant as a sodium ion adsorbent. Since the silica gel that is highly transparent is used as the sodium ion adsorbent, it is possible to prevent PID attributable to sodium ions and to prevent deterioration in photovoltaic efficiency of the photovoltaic module. Since the silica gel has a high specific surface area, it is possible to adsorb sodium ions with a small amount of the silica gel.

  • Publication number: 20170125618
    Abstract: Disclosed is a method of forming a CIGS-based thin film having high efficiency using a simple process at relatively low temperatures. The method includes an Ag thin film forming step and an ACIGS forming step of depositing Cu, In, Ga, and Se on the surface of the Ag thin film using a vacuum co-evaporation process. Ag, constituting the Ag thin film, is completely diffused, while Cu, In, Ga, and Se are deposited to form ACIGS together with Cu, In, Ga, and Se co-evaporated in a vacuum during the ACIGS forming step. The Ag thin film is formed and CIGS elements are then deposited using vacuum co-evaporation to form an ACIGS thin film having improved power generation efficiency at a relatively low temperature of 400° C. or less using only a single-stage vacuum co-evaporation process.
