    • An improved process for producing a light-absorbing chalcopyrite film is disclosed, which comprises the steps of: applying at least one solution containing at least either of (a) an organic compound of a metal in Group 1B of the periodic table and (b) an organic compound of a metal in Group 3B of the periodic table on a substrate at least once to thereby form a thin film containing the organic compound (a) and the organic compound (b); heating the thin film in a reducing or inert gas atmosphere to convert the thin film into a thin metal film comprising the Group 1B metal and the Group 3B metal; and heating the thin metal film in an atmosphere containing either an element in Group 6B of the periodic table or a compound thereof to thereby convert the thin metal film into a thin chalcopyrite film. This process eliminates the problem concerning the control of the composition and thickness of a light-absorbing chalcopyrite film, and is suitable for the mass production of homogeneous large light-absorbing plates for use in solar cells.
    • 公开了一种用于制备光吸收黄铜矿膜的改进方法,其包括以下步骤:施加至少一种至少一种包含(a)元素周期表第1B族中的(a)金属有机化合物和(b) 在基板上的元素周期表3B中的金属的有机化合物至少一次,从而形成含有有机化合物(a)和有机化合物(b)的薄膜; 在还原或惰性气体气氛中加热薄膜以将薄膜转变成包含1B族金属和3B族金属的薄金属膜; 并在含有元素周期表第6B族元素或其化合物的气氛中加热薄金属膜,从而将薄金属膜转变为薄黄铜矿膜。 该方法消除了关于光吸收性黄铜矿膜的组成和厚度的控制的问题,并且适用于批量生产用于太阳能电池的均匀的大型吸光板。

    • An underwater granulating method in which thermoplastic resin material is kneaded and melted by a kneading extruder while the melted resin material is extruded into cooling water from nozzles of a die with its external surface covered with the cooling water, and the resin material extruded in thin strings is cut by a cutter device driven to move along the external surface of the die. The method is characterized by the following steps: increasing the heating magnitude of the die so that the softened resin material filling the neighborhood of the external surface of the nozzles is melted; temporarily stopping the kneading extruder in the heating state where the kneading extruder is supplied with resin material; stopping the cutter device; reducing the heating quantity of the die; covering the external surface of the nozzles with the cooling water in the condition where the resin material filling the neighborhood of the external surface in the nozzles is softened to close the nozzles; and thereafter starting the drive of the cutter device and, at the same time, the drive of the kneading extruder.
    • 一种水下造粒方法,其中将热塑性树脂材料通过捏合挤出机捏合并熔化,同时将熔融的树脂材料从其外表面被冷却水覆盖的模具的喷嘴挤出到冷却水中,并且将树脂材料挤压成细绳 被切割装置切割,该切割装置被驱动以沿模具的外表面移动。 该方法的特征在于以下步骤:增加模具的加热幅度,使得填充喷嘴外表面附近的软化树脂材料熔化; 在捏合挤出机被供给树脂材料的加热状态下临时停止捏合挤出机; 停止切割装置; 降低模具的加热量; 在填充喷嘴外表面附近的树脂材料软化以封闭喷嘴的状态下用冷却水覆盖喷嘴的外表面; 然后开始切割装置的驱动,同时驱动捏合挤出机。
