Description

태양광전지의 측정기 장치{TESTER OF SOLAR CELL}Measuring device of photovoltaic cell {TESTER OF SOLAR CELL}

본 발명은 태양광전지의 측정기 장치에 관한 것으로서, 보다 상세히는 태양광전지의 전기적인 성능을 측정하는 측정기의 내부 온도를 일정하게 하는 태양광전지의 측정기 장치에 관한 것이다.The present invention relates to a measuring device of a solar cell, and more particularly to a measuring device of a photovoltaic cell for maintaining the internal temperature of the measuring device for measuring the electrical performance of the photovoltaic cell.

현재 일반적인 태양광전지의 생산에 있어서 태양광전지의 측정부분은 제품의 가격을 결정짓는 중요한 요소이다. 그 측정의 기준은 국제화 되어 있다. 그러나 산업현장에서 고속으로 측정이 이루어지는 바, 도 1을 참조하면, 측정기(10) 내에 태양광전지(12)를 두고 램프(15)를 방사한다. 그 결과 연속된 램프(15)의 방사에 의해 측정기(10) 내부의 온도가 증가한다. 그러므로, 변화되는 측정기의 온도에 대한 보정계수(TKI, TKU)를 필요로 한다. 그러나 산업 현장에 설치된 태양광전지의 측정기는 대부분 온도에 대한 변수에 대응하지 못하고 있다.In the production of general photovoltaic cells, the measurement part of photovoltaic cells is an important factor that determines the price of products. The standard of measurement is internationalized. However, since the measurement is performed at high speed in the industrial field, referring to FIG. 1, the lamp 15 is radiated with the photovoltaic cell 12 in the meter 10. As a result, the temperature inside the meter 10 increases due to the continuous radiation of the lamp 15. Therefore, a correction factor (TKI, TKU) for the temperature of the changing instrument is required. However, most of the solar cell meter installed in the industrial field does not respond to the temperature variable.

본 발명은 상술한 종래의 문제점을 극복하기 위한 것으로, 본 발명의 목적은 태양광 발전용 태양광전지 생산공정 중 제조된 태양광전지의 전기적인 성능을 측정함에 있어서 측정기 내의 온도를 일정하게 유지하여 태양광전지의 전기적인 특성을 정확히 측정 할 수 있는 태양광전지의 측정기 장치를 제공하는데 있다.The present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to maintain a constant temperature in the meter in the measurement of the electrical performance of the photovoltaic cell produced during photovoltaic photovoltaic cell production process photovoltaic cells It is to provide a photovoltaic cell measuring device that can accurately measure the electrical characteristics of.

본 발명에 따른 태양광전지의 측정기 장치의 일예로서,As an example of the measuring device of the solar cell according to the present invention,

태양광전지에 램프를 방사하면서 태양광전지의 전기적 특성을 측정하는 측정기에 있어서,In the measuring device for measuring the electrical characteristics of the solar cell while emitting a lamp to the solar cell,

측정기 내에서 가열과 냉각을 동시에 이루기 위해 열전소자를 더 구비하고, 측정기 내의 온도를 측정하고 열전소자를 구동하는 온도 컨트롤러를 설치하여 측정기 내부의 온도를 일정한 온도로 유지한다.A thermoelectric element is further provided to simultaneously heat and cool the inside of the meter, and a temperature controller for measuring the temperature in the meter and driving the thermoelectric element is installed to maintain a constant temperature inside the meter.

본 발명에 따른 태양광전지의 측정기 장치는 측정기에서 연속적인 측정이 이루어져도 태양전지 측정기 내부의 온도는 일정하게 유지되어, 정확하게 태양광전지의 전기적인 특성치를 측정할 수 있게 되고, 측정기 내부의 냉각과 가열을 하나의 열전 소자를 이용하여 실행하므로 온도 보정 수단이 간편하다는 효과가 있다.In the solar cell measuring device according to the present invention, even if continuous measurement is made in the measuring device, the temperature inside the solar cell measuring device is kept constant, so that the electrical characteristics of the solar cell can be accurately measured, and the cooling and heating inside the measuring device Since the operation is performed using one thermoelectric element, there is an effect that the temperature correction means is simple.

여기에서 설명한 것은 본 발명에 따른 태양광전지의 측정기 장치를 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 발명은 본 실시예에 한정되지 않고, 이하의 특허청구의 범위에서 청구하는 바와 같이 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능한 범위까지 본 발명의 기술적 정신이 있다고 할 것이다.What has been described herein is just one embodiment for carrying out the solar cell measuring device according to the present invention, and the present invention is not limited to the present embodiment, and as claimed in the following claims, Without departing from the gist of the present invention, one of ordinary skill in the art will have the technical spirit of the present invention to the extent that various modifications can be made.

이하, 본 발명의 실시예를 첨부 도면을 참조하여 설명하기로 한다. Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

도 2를 참조하면, 측정기(10) 내에 태양광전지(12)를 두고 램프(15)를 방사한다. 그 결과 연속된 램프(15)의 방사에 의해 측정기(10) 내부의 온도가 증가한다. 그러므로, 변화되는 측정기의 온도에 대한 보정계수(TKI, TKU)를 필요로 한다. Referring to FIG. 2, the lamp 15 is radiated with the photovoltaic cell 12 in the meter 10. As a result, the temperature inside the meter 10 increases due to the continuous radiation of the lamp 15. Therefore, a correction factor (TKI, TKU) for the temperature of the changing instrument is required.

본 발명은 열전소자(25)를 구비한다. 열전소자는 (Thermoelectric module)은 n, p type 열전반도체(Thermoelectric semiconductor)를 전기적으로는 직렬로 열적으로는 병렬로 되도록 연결한 모듈의 형태로 사용된다. DC 전류를 흘렸을 때는 열전효과에 의해서 모듈의 양면에 온도차가 발생하고, 동시에 발전현상이 일어나게 된다. 일반적으로 펠티어(Peltier) 현상에 의해 나타나는 냉각효과를 이용하는 고체식 히트 펌프(solid state heat pump)를 말한다. 냉매를 순환시키기 위해 압축기를 가동시키는 기존의 냉각방식을 탈피한 차세대 냉각방식으로서 극전환( + , - )을 통해 어디든지 간편하게 냉각과 가열이 동시에 가능하여 상온에서 대상물을 - 30℃에서 +180℃ 까지 냉각과 가열을 통해 일정 온도로 유지되게 하게 할 수 있다.The present invention includes a thermoelectric element (25). The thermoelectric module is used in the form of a module in which n, p type thermoelectric semiconductors are electrically connected in series and thermally in parallel. When the DC current flows, a temperature difference occurs on both sides of the module due to the thermoelectric effect, and power generation occurs at the same time. Generally refers to a solid state heat pump (solid state heat pump) using the cooling effect exhibited by the Peltier phenomenon. It is a next-generation cooling method that escapes the existing cooling method that operates the compressor to circulate the refrigerant. It can be simultaneously cooled and heated anywhere through polar switching (+,-), and the object can be cooled at -30 ℃ to + 180 ℃. Can be maintained at a constant temperature through cooling and heating.

측정기(10)의 측정온도가 25℃로 일정하게 유지 된다면 별 다른 문제점이 발생하지 않을 것이다. 온도를 보정하기 위해선 25℃ 보다 낮을 때, 높을 때 2가지 경우에 대해서 보상을 해주어야 한다. 제한된 공간에서 가열과 냉각을 동시에 이루기 위해 열전소자(25)를 사용하고 온도를 측정하고 열전소자(25)를 구동하는 온도 컨트롤러(20)를 설치하여 측정기(10) 내부의 온도를 일정한 온도로 유지할 수 있다.If the measuring temperature of the measuring device 10 is kept constant at 25 ℃ will not cause other problems. To calibrate the temperature, two cases must be compensated for when it is lower than 25 ° C and higher. In order to keep heating and cooling at the same time in a limited space, the temperature controller 20 is installed to measure the temperature and drive the thermoelectric element 25 to maintain the temperature inside the meter 10 at a constant temperature. Can be.
