본 고안은 소용량 태양전지 모듈을 제조하는 데 있어서 필요한 전압과 전류를 발생시키기 위해 웨이퍼 형태의 셀에서 일정한 크기로 절단된 각각의 셀들을 인쇄 회로 기판에 배치하고 각기 셀의 음극과 양극을 인쇄 회로 기판의 패턴을 통하여 순차적으로 연결시켜 도통 됨으로써 기전력이 발생토록 하는 태양전지 모듈 제품과 이의 제조 방법에 관한 것이다.  The present invention places each cell cut to a certain size in a wafer-shaped cell on a printed circuit board to generate the voltage and current required to manufacture a small capacity solar cell module, and the cathode and the anode of each cell are printed circuit boards. The present invention relates to a solar cell module product and a method of manufacturing the same, in which electromotive force is generated by being sequentially connected through a pattern of.

종래에는 태양전지 셀을 연결할 때 금속으로 이루어진 태양전지용 리본을 사용하여 셀의 상호 극성이 연결되도록 하는데, 이는 특히 소용량 태양전지 모듈의 경우 많은 시간이 소요되는 어려움과 작업과정이 복잡하여 상대적으로 높은 불량 발생을 감수하여야 한다.  Conventionally, when the solar cell is connected, the polarity of the cells is connected by using a metal ribbon for the solar cell, which is particularly high in the case of a small capacity solar cell module, which requires a lot of time and complicated work processes. You must bear the occurrence.

또한 이러한 제조 방식은 자동화 장치를 제작하는데 있어서도 많은 문제점이 있어 기술적으로나 경제적인 손실이 크다.In addition, such a manufacturing method has a lot of problems in manufacturing an automated device, so the technical and economic losses are large.

본 고안은 상기한 소용량 태양전지 모듈을 제조하는 단계에서 태양전지 셀 들을 직렬 혹은 병렬로 연결하는 데 있어, 태양전지용 리본이나 금속 와이어 등을 사용하지 않고 플렉시블 피씨비(FPCB)을 활용하여 태양전지 셀의 수량에 관계없이 각각의 셀 극성을 일시에 연결, 도통 되게 함으로서 소용량 태양전지 모듈을 제조하는데 따른 생산 효율을 대폭 올릴 수 있을 뿐만 아니라, 특히 자동화 장치 개발을 용이하게 할 수 있도록 하는데 그 목적이 있다.  The present invention is to connect the solar cells in series or parallel in the step of manufacturing the small-capacity solar cell module, using a flexible PCB (FPCB) without using a ribbon or metal wire for solar cells of the solar cell By connecting and conducting each cell polarity at any one time irrespective of the quantity, it is possible not only to greatly increase the production efficiency for manufacturing a small capacity solar cell module, but also to facilitate the development of an automation device.

본 고안은 금속 페이스트가 도포 된 인쇄 회로 기판 위에 소요되는 태양전지 셀을 차례로 올리고 이들 셀과 연결된 인쇄 회로기판의 패턴의 극성과 셀 들의 극성을 접착용 페이스트를 바른 플렉시블 피씨비(FPCB)를 이용하여 연결함으로써 모듈의 전체적인 도통을 이루게 한다.  The present invention raises the solar cells required on the printed circuit board coated with metal paste and connects the polarities of the patterns of the printed circuit boards connected to these cells with the flexible pastes (FPCB) coated with adhesive paste. By doing so, it is possible to achieve the overall conduction of the module.

또한, 베이스로 이용되는 인쇄 회로 기판을 사용하지 않고 플렉시블 피씨비(FPCB) 만으로도 제작이 가능하다. In addition, it is possible to manufacture only a flexible PC (FPCB) without using a printed circuit board used as a base.

즉 필요한 패턴이 인쇄되어 있는 플렉시블 피씨비(FPCB) 위에 접착용 금속 페이스트를 바른 후, 태양전지 셀을 배치하고 플렉시블 피씨비(FPCB)를 접어 가열 접착함으로서 도통 되도록 하면 된다.That is, after apply | coating an adhesive metal paste on the flexible PCB (FPCB) in which the necessary pattern is printed, solar cell is arrange | positioned, the flexible PC (FPCB) is folded, and heat-bonding may be conducted.

첫째, 태양전지 셀 들의 극성을 연결하는데 태양전지용 리본이나 금속 와이어 등으로 하나하나 일일이 작업하여야 하는 번거러움이 없이 몇 개의 셀이 구성되든 플렉시블 피씨비(FPCB)로 동시에 연결이 가능하여 시간적인 절약이 가능하며, 간결한 제조 방법으로 불량 발생이 현저히 저감되는 효과를 갖는다.First, it connects the polarity of solar cells without the hassle of working one by one with ribbon or metal wire for solar cell, and can be connected simultaneously with flexible PCB (FPCB) regardless of how many cells are composed. This has the effect of significantly reducing the occurrence of defects with a simple manufacturing method.

둘째, 플렉시블 피씨비(FPCB) 만으로 제조하는 경우에는 자체 중량을 줄일 수 있어 경량화를 꾀할 수 있을 뿐만 아니라, 인쇄 회로 기판의 사용을 배제함으로써 자재절감이 가능하고, 태양전지 모듈의 표면을 곡면으로 제조할 수 있는 효과를 갖는다.Second, in the case of manufacturing only the flexible PCB (FPCB), it can reduce its own weight to reduce the weight, and it is possible to save material by eliminating the use of a printed circuit board, and to make the surface of the solar cell module curved. Has the effect.

셋째, 이러한 제조 방법은 자동화 장치를 개발하는 경우 용이하게 활용할 수 있는 Third, this manufacturing method can be easily utilized when developing an automated device.

우수한 효과를 갖는다.Has an excellent effect.

상기한 목적을 달성하기 위한 기술적 구성으로서 본 고안은 인쇄 회로 기판 위에 배치한 태양전지 셀 들을 플렉시블 피씨비(FPCB)를 이용하여 차례로 연결, 도통 되게 하는 것을 특징으로 한다.  As a technical configuration for achieving the above object, the present invention is characterized in that the solar cells disposed on a printed circuit board are connected and connected in sequence by using a flexible PCB (FPCB).

태양으로부터 발생하는 빛 에너지를 전기 에너지로 변환시키는 태양전지 소자를 이용하기 위하여, 태양전지 셀을 직렬 혹은 병렬로 연결하여 필요한 전압과 전류를 발생토록 하여 이를 활용케 되는데 소용량의 태양전지 모듈에 있어서는 통상적인 방법으로 연결 부품인 태양전지용 리본으로 부착, 연결하고 있다. 이 리본으로 연결된 상태를 인쇄 회로 기판 위에 고정하는 방식으로 하고 있으나, 이러한 방식은 시간적, 경제적인 손실과 더불어 많은 불편함이 있다.In order to use a solar cell device that converts light energy generated from the sun into electrical energy, solar cells are connected in series or in parallel to generate necessary voltages and currents. It attaches and connects with the ribbon for solar cell which is a connection part by the method. Although the state connected by the ribbon is fixed on the printed circuit board, this method has a lot of inconveniences with time and economic loss.

이 태양전지 모듈에 있어서 절단된 셀의 크기에 따라 전류량은 확정되어 있으므로 필요한 전압을 발생하도록 구성하기 위해 소요되는 수량만큼 접합시켜야 하며, 이 태양전지 셀(10)의 직렬 연결이 이루어져야 하기 때문에 각 태양전지 셀(10)의 밑면과 상부의 접합면(11)은 상호 반대의 극성을 갖고 있어 이들을 교차로 차례차례 연결해 주어야 하는데 이때 일반적인 태양전지용 리본이나 금속류 와이어 형태로는 셀과 셀, 셀과 인쇄 회로 기판상의 패턴 연결을 하나하나 해 주어야 하는 방식은 제조시간이 많이 소모된다.In this solar cell module, since the amount of current is determined according to the size of the cut cell, it is required to be bonded as much as necessary to configure to generate the required voltage, and each solar cell 10 has to be connected in series. The bottom surface of the battery cell 10 and the junction surface 11 of the upper side have opposite polarities, and they need to be connected to each other in turn. In this case, in the form of a general solar ribbon or metal wire, the cell and the cell, the cell and the printed circuit board The method of connecting the pattern of the phases one by one consumes a lot of manufacturing time.

회로가 인쇄된 플렉시블 피씨비(30)의 접합부위에 금속 페이스트(21)를 바르고 이를 태양전지 셀(10)의 접합면(11)과 인쇄회로기판(20)의 패턴 위의 정위치에 올려놓는다. 이 상태에서 플렉시블 피씨비(30) 위치에 가열하게 되면 금속 페이스트(21)가 용해되어 각각의 전극을 접합, 도통이 이루어진다.The metal paste 21 is applied to the junction of the flexible PCB 30 on which the circuit is printed and placed on the junction surface 11 of the solar cell 10 and the pattern of the printed circuit board 20. In this state, when heated to the position of the flexible PC 30, the metal paste 21 is dissolved to join and conduct the electrodes.

제 2 도는 본 고안에 따른 베이스 기판이 없는 제조 방법을 도시한 외형도이다.2 is an outline view showing a manufacturing method without a base substrate according to the present invention.

소용량의 태양전지 모듈에서 통상적으로 베이스로 사용되는 인쇄 회로 기판(20)을 사용하지 않고 제조하는 방법으로, 태양전지 셀(10)의 극성이 연결될 수 있도록 회로가 설계되고, 접어질 수 있는 플렉시블 피씨비(31)의 접합 패턴(32)에 금속 페이스트(21)를 바르고 태양전지 셀(10)을 차례로 올려놓는다.In a method of manufacturing without using a printed circuit board 20 commonly used as a base in a small capacity solar cell module, the circuit is designed so that the polarity of the solar cell 10 can be connected, and the flexible PC can be folded The metal paste 21 is applied to the bonding pattern 32 of 31, and the solar cell 10 is placed in order.

접어질 수 있는 플렉시블 피씨비(31)를 접은 후 가열하면 마찬가지로 금속 페이스트(21)가 용해되어 접착이 이루어지며 도통이 하게 된다.When the folded flexible PCB 31 is folded and then heated, the metal paste 21 is similarly dissolved to form an adhesive, and thus conduction occurs.

제 4 도는 본 고안에 따른 태양전지 모듈의 상태도이다.4 is a state diagram of a solar cell module according to the present invention.

일반적으로 부스바라고 하는 리본 접합부를 검점 테이프로 붙여 가리는 경우가 있는데,In general, a ribbon joint called a busbar is covered with a check tape.

상기한 방법에 따라 제조된 소용량 태양전지 모듈은 필요에 따라 플렉시블 피씨비(30)의 색상을 검정색으로 도장하여 제조할 수 있다. 이 경우 별도의 검정 테이프를 바르는 노력을 하지 않는 효과를 갖는다.The small capacity solar cell module manufactured according to the above method may be manufactured by coating the color of the flexible PC 30 in black as needed. In this case, it does not make an effort to apply a separate black tape.
