摘要:
The invention relates to a dye-sensitized solar cell and a module using the same and more particularly, to a dye-sensitized solar cell in which a photoelectrode substrate and a catalyst electrode substrate are spaced apart from each other by a separating space and coupled together by an encapsulating material and the separating space is filled with an electrolyte, characterized in that the electrolyte contains optical beads, and a module using the same. Thus, light passing through the photoelectrode substrate is refracted or reflected by the optical beads, and irradiated onto the photoelectrode substrate, thereby to improve the efficiency of the solar cell. Particularly, the efficiency of a dye-sensitized solar cell for a BIPV system is more effectively improved, said solar cell not having a separate scattering layer for maintaining the translucency thereof. If the optical beads are colored, solar cells with a variety of colors can be obtained, which achieves an aesthetic enhancement for a building adopting the BIPV system.
摘要:
A method for manufacturing a capacitor of a semiconductor memory device is provided. A first insulating layer and a second insulating layer are formed in sequence on a semiconductor substrate on which a transistor including a source region, a drain region and a gate electrode, and a buried bit-line surrounded by insulating layer are formed. Then, a contact hole is formed by sequentially etching the layers stacked on the source region, by which the source region of the transistor is exposed, and a spacer made of an insulating substance is formed inside the contact hole, and a first conductive layer is formed on the whole surface of the resultant. Next, the first conductive layer and second insulating layer are etched, and a second conductive layer is formed on the whole surface of the resultant, and a storage electrode is formed by etching the second conductive layer using the first conductive layer as a mask. According to the method, the step for forming the contact hole is very simple and less photolithography steps are required since the first conductive layer is used as a mask for etching the second conductive layer, thereby simplifying the manufacturing process.

A method is provided for manufacturing a capacitor of a semiconductor device. First, an insulating layer, an etching barrier layer, a first material layer and a second material layer are sequentially stacked on a semiconductor substrate on which a field oxide layer and a gate electrode are formed, and predetermined portions of the stacked layers are sequentially etched to form a contact hole exposing the substrate. Then, a first conductive layer is formed on thge whole surface of the resultant structure having the contact hole. Subsequently, a storage electrode pattern is formed by patterning the first conductive layer and etching the second material layer. Then, a second conductive layer is formed on the whole surface of the resultant structure so as to cover the storage electrode pattern and the first material layer. Thereafter, the second conductive layer is etched to expose the upper surface of the storage electrode pattern. Therefore, the capacitor manufacturing process, particularly, the etching process, is simplified, and can be applied to a capacitor having a COB structure.
