Description
본 발명은 인공위성용 태양전지의 커버그래스 접지방법에 관한 것으로서, 특히 인공위성의 태양전지에 구비된 커버글래스(Cover Grass)에 실버파스터(Silver Paste)를 페인팅(Painting)시켜 솔라셀(Solar Cell)을 접지시키도록 한 인공위성용 태양전지의 커버그래스 접지방법에 관한 것이다.The present invention relates to a method for grounding a cover glass of a satellite solar cell, and in particular, a silver paste on a cover glass provided in a solar cell of a satellite, thereby painting a solar cell. It relates to a cover grass grounding method of a solar cell for satellites to be grounded.
일반적으로 인공위성의 태양전지는 태양광선의 에너지를 변환시켜 전기에너지로 이용하는 반도체 광기전소자(光起電素子)를 말한다.In general, a satellite solar cell refers to a semiconductor photovoltaic device that converts energy of sunlight into electric energy.
상기한 태양전지에는 솔라셀과 이에 적층 구비되는 커버그래스가 상호 접지된 상태로 구비되어 있고, 커버그래스는 솔라셀을 보호하기 위한 기능을 갖고 있다.The solar cell is provided with a solar cell and a cover grass stacked on the solar cell, and the cover grass has a function for protecting the solar cell.
이와같이 된 종래의 커버그래스(CG)를 설명하면 도 1에서 보는 바와같이 상부 일정부위의 측부에 전극(P)를 가진 솔라셀(SC)의 표면에 접착제(E)를 도포하고, 이 상부에 커버그래스(CG)가 적층구비된다.Referring to the conventional covergrass CG thus obtained, as shown in FIG. 1, the adhesive E is applied to the surface of the solar cell SC having the electrode P on the side of the upper predetermined portion, and the cover is covered on the upper portion. Grass CG is laminated.
상기 커버그래스(CG)의 상부면 표면에는 ITO층(Indium Tin Oxide Coating)이 구비된다.An ITO layer (Indium Tin Oxide Coating) is provided on the top surface of the covergrass CG.
상기 ITO층(C1)이 구비된 커버그래스(CG)의 측면에는 별도의 ITO 코팅층이 구비된 클립(CL)을 구비하여 솔라셀(SC)의 전극(P)와 ITO층(C1)을 접지시키도록 한다.A side of the cover grass CG having the ITO layer C1 is provided with a clip CL having a separate ITO coating layer to ground the electrode P of the cell SC and the ITO layer C1. To do that.
클립(CL)의 ITO 코팅층은 접지력을 좋게 하기 위해 에코본드(Ecco Bond : 전도성 에폭시)와 니켈 및 크롬 등이 사용된다.The ITO coating layer of the clip CL is used with Eco Bond (conductive epoxy), nickel, chromium, etc. to improve the grounding force.
이러한 클립(CL)은 접지성을 좋게 하기 위해 진공증착장비를 이용한 ITO 코팅층을 구비함에 따라 코팅공정이 매우 복잡하였다.The clip (CL) has a very complicated coating process as it has an ITO coating layer using a vacuum deposition equipment to improve the grounding properties.
즉, 진공챔버(Chamber)내에서 코팅하고자 하는 물질을 녹인후 증발시키기 위하여 진공챔버의 진공도를 높이는 펌핑다운(Pumping Down) 시간과 코팅물질을 융점이상의 온도로 가열하기 위한 시간의 소요가 많음에 따라 공정시간이 매우 길게 유지된다.That is, the pumping down time for increasing the vacuum degree of the vacuum chamber and the time required for heating the coating material to a temperature above the melting point in order to melt and evaporate the material to be coated in the vacuum chamber (Chamber) The process time is kept very long.
또한 ITO 코팅층을 가진 별도의 클립(CL)을 솔라셀(SC)의 전극(P)와 커버그래스(CG)의 ITO층(C1) 사이에 접지되도록 설치할 때 클립(CL)의 설치 결합 작업성이 용이하지 못하였고, 별도의 클립(CL) 사용에 의한 제조원가 상승을 유발시켰으며, 생산성을 저하시키는 문제점이 있었다.In addition, when the separate clip CL having the ITO coating layer is grounded between the electrode P of the solar cell SC and the ITO layer C1 of the covergrass CG, the installation coupling workability of the clip CL is It was not easy, causing a rise in manufacturing cost by using a separate clip (CL), there was a problem of lowering the productivity.
본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 발명한 것으로 인공위성에 적용되는 태양전지의 커버글래스에 전도성의 실버파스터를 페인팅시켜 솔라셀의 전극와 커버글래스에 구비된 ITO 층과의 접지를 용이하게 한 것을 목적으로 한다.The present invention has been invented to solve the above-mentioned conventional problems, and the grounding of the solar cell cover glass applied to the satellite by painting a conductive silver paste to facilitate the grounding of the solar cell electrode and the ITO layer provided on the cover glass. It is intended to be made.

인공위성의 솔라셀(SC)에 구비된 전극(P)와 커버그래스(CG)에 구비된 ITO층(C1)을 접지시키기 위해 ITO 코팅층이 코팅된 별도의 클립(CL)을 설치한 것에 있어서,In the installation of a separate clip (CL) coated with an ITO coating layer in order to ground the electrode (P) provided in the solar cell (SC) of the satellite and the ITO layer (C1) provided in the covergrass (CG),
상기 솔라셀(SC)의 전극(P)와 커버그래스(CG)의 ITO층(C1) 사이의 커버그래스(CG) 측면에 실버파스터(SP)를 페인팅시킨 것이다.The silver paste SP is painted on the side of the covergrass CG between the electrode P of the solar cell SC and the ITO layer C1 of the covergrass CG.
이와 같이된 본 발명의 일실시예를 첨부도에 의하여 상세히 설명하면 다음과 같다.When described in detail by the accompanying drawings an embodiment of the present invention as follows.
도 2는 본 발명의 구성도로서 인공위성에 구비되는 솔라셀(SC)의 상부면에 접착제(E)와 단부에 전극(P)을 구비하고, 이 상부에 커버그래스(CG)를 접착구비하며, 커버그래스(CG)의 표면에는 ITO층(C1)을 구비하고, ITO층(C1)과 솔라셀(SC)에 구비된 전극(P)와의 접지를 위해 커버글래스(CG)의 측면에 실버파스터(은 + 접착제)를 페인팅한다.Figure 2 is a block diagram of the present invention is provided with an adhesive (E) and the electrode (P) on the upper surface of the solar cell (SC) provided in the satellite, and the cover glass (CG) in the upper portion, The surface of the cover glass CG is provided with an ITO layer C1, and a silver paste is formed on the side of the cover glass CG for grounding between the ITO layer C1 and the electrode P provided in the solar cell SC. Paint (silver + glue).
상기 실버파스터(SP)는 은과 접착제를 혼합시킨 상태에서 솔라셀(SC)의 전극(P)와 ITO층(C1)과 접촉되는 범위로 커버그래스(CG)에 페인팅함에 따라 태양전지의 접지기능 작업성을 용이하게 한다.The silver paste (SP) is grounded in the solar cell by painting on the cover grass (CG) in a range in contact with the electrode (P) of the solar cell (SC) and the ITO layer (C1) in a state where silver and an adhesive are mixed. Facilitate functional workability.
따라서 종래와 같이 클립(CL)에 도포된 ITO 코팅층을 구하기 위한 별도의 진공 증착기의 배제와 간단한 실버파스터(SP)의 페인팅 작업으로 제작단가를 저감시킬 수 있다.Therefore, the manufacturing cost can be reduced by eliminating the separate vacuum evaporator for obtaining the ITO coating layer applied to the clip CL and the simple painting of the silver paste SP.
또한 전도체 물질을 갖고 있는 실버파스터(SP)의 전기저항이 기존의 ITO 코팅층 보다 작으므로 전류의 흐름을 원활하게 하여 전기적 특성 증대와 접지력의 향상을 기할 수 있는 것이다.In addition, since the electrical resistance of the silver paste (SP) having a conductor material is smaller than that of the conventional ITO coating layer, the current flows smoothly, thereby improving electrical characteristics and improving grounding power.
이상에서와 같이 본 발명은 인공위성에 적용되는 태양전지의 커버글래스에 전도성의 실버파스터를 페인팅시켜 솔라셀의 전극와 커버글래스에 구비된 ITO 층에 접지되게 하므로서 전기적 특성 기능을 향상시키고, 태양전지의 접지작업성 향상과 제작단가를 절감시킬 수 있는 효과가 있다.As described above, the present invention paints a conductive silver paste on the cover glass of the solar cell applied to the satellite, thereby improving the electrical characteristics by grounding the electrode and the ITO layer provided on the cover glass. There is an effect that can improve the ground workability and reduce the manufacturing cost.
