Abstract:
PURPOSE: An organic-inorganic hybrid type tandem solar cell and a method of fabricating the same are provided to increase photoelectric conversion efficiency by differently controlling the band gap of a p-type semiconductor compound and the band gap of a hole receptor. CONSTITUTION: In an organic-inorganic hybrid type tandem solar cell and a method of fabricating the same, a p-type semiconductor layer, a first buffer, and a ZnO n-type semiconductor are laminated on a metal electrode to form a chalcogenide group solar cell. A connection layer(106) is formed on the solar cell. A second buffer layer is formed on the connection layer and a single and plurality of thin films to form an organic solar cell. A protective layer(110) is formed on the organic solar cell and a transparent electrode on the protective film.
Abstract:
A vacuum injection device for injecting liquid crystal and a method thereof are provided to fabricate PDLC having uniform characteristic by preventing volatilization of the polymerization material. A liquid crystal boat(20) installed inside of a vacuum chamber(30) has one or more opening(22) on one side. The liquid crystal boat contains liquid crystal(23). The vacuum chamber and an inside of a liquid crystal cell are vacuum pumped at the same time. A cover(21) opens and closes the opening by preventing volatilization of the liquid crystal which is contained by being connected to the liquid crystal boat.
