As shown in the figure, the solar cell module 100 according to the present invention comprises a solar cell array 110 and an external protector 120.
상기 태양전지셀 배열(110)은 다수의 태양전지 셀(Solar cell)(111)이 배열되되, 광 투과성 충진접착제(112)에 의해 피복되고 상기 외부 보호체(120) 내부에 접착된다. 태양전지모듈(100)의 발전 용량에 따라, 태양전지 셀(111)의 갯수가 결정되며, 각 태양전지 셀(111)은 이웃하는 태양전지 셀과 리드선(113)에 의해 연결되며, EVA(Ethylene Vinyl Acetate) 등의 광 투과성 충진접착제(112)에 의해 충진되어 피복됨으로써 태양전지 셀들이 외부로부터 보호된다.The solar cell array 110 has a plurality of solar cells 111 are arranged, and is covered by a light-transmissive filler adhesive 112 and adhered to the outer protector 120.

However, since the fixing structure is a use case part that can be selected in various ways, a detailed description thereof will be omitted.
따라서, 위와 같이함에 의해, 본 발명은 태양전지셀 배열(110)이 투명 단열성 재질의 외부 보호체(120)로 밀봉 수납되도록 구현되어 태양전지셀 배열이 외부의 높은 온도 환경과 격리됨으로써 태양전지의 발전 효율을 향상 및 증대시킬 수 있게 되므로, 상기에서 제시한 본 발명의 목적을 달성할 수 있게 된다.Therefore, by the above, the present invention is implemented so that the solar cell array 110 is sealed and received by the outer protective body 120 of the transparent heat insulating material so that the solar cell array is isolated from the external high temperature environment of the solar cell Since the power generation efficiency can be improved and increased, the object of the present invention as described above can be achieved.
한편, 본 발명의 부가적인 양상에 따르면, 상기 외부 보호체(120)가 그 내부에 상기 태양전지셀 배열(110)을 냉각시키기 위한 냉기를 수납하는 냉기실(123)을 구비할 수 있다. 즉, 이 실시예는 외부 보호체(120)에 냉기를 수납하여 공냉식으로 태양전지셀 배열(110)을 냉각시킴으로써 발전 효율을 향상 및 증대시킬 수 있도록 한 실시예이다.Meanwhile, according to an additional aspect of the present invention, the outer protector 120 may include a cold air chamber 123 accommodating cold air for cooling the solar cell array 110 therein. That is, this embodiment is an embodiment in which the cold air is stored in the outer protector 120 to cool and the solar cell array 110 is cooled by air cooling to improve and increase power generation efficiency.
상기 외부 보호체(120)가 투명 단열성 재질이므로, 냉기실(123)의 냉기가 한번 냉각되면, 냉기실(123)내의 온도는 오랫동안 저온 상태가 유지되게 되고, 이로인해 태양전지셀 배열(110)을 지속적으로 냉각시킬 수 있게 된다.Since the outer protector 120 is a transparent heat insulating material, once the cold air in the cold chamber 123 is cooled once, the temperature in the cold chamber 123 is maintained at a low temperature for a long time, and thus, the solar cell array 110 is provided. Can be cooled continuously.
예컨대, 상기 냉기실(123)은 도 1, 도 3 및 도 4 에 도시한 바와 같이, 내부 공간이 하나인 단일 구조의 외부 보호체(120) 내부에 형성한 공간일 수도 있으며, 도 2 에 도시한 바와 같이, 내부 공간이 2개 이상인 복합 구조의 외부 보호체(120) 내부에 형성한 공간일 수도 있다.For example, as illustrated in FIGS. 1, 3, and 4, the cold air chamber 123 may be a space formed inside the outer protector 120 having a single internal structure having a single internal space. As described above, it may be a space formed inside the outer protector 120 of the composite structure having two or more internal spaces.
한편, 본 발명의 부가적인 양상에 따르면, 상기 태양전지모듈이 냉각부(130)를 더 포함할 수 있다. 상기 냉각부(130)는 상기 냉기실(123)의 냉기 온도를 낮추기 위한 구성으로, 냉기실(123) 내부의 냉기의 온도를 낮추어 대류 현상에 의해 외부 보호체(120) 내부의 태양전지셀 배열(110)의 온도를 낮추어 발전 효율을 향상 및 증대시킬 수 있도록 한 실시예이다.Meanwhile, according to an additional aspect of the present invention, the solar cell module may further include a cooling unit 130. The cooling unit 130 is configured to lower the temperature of the cold air in the cold chamber 123, and lowers the temperature of the cold air in the cold chamber 123 to convex a solar cell array inside the outer protector 120. The embodiment of the present invention is to reduce the temperature of 110 to improve and increase power generation efficiency.
예컨대, 상기 냉각부(130)가 도 1 에 도시한 바와 같이 상기 냉기실(123)로 냉기를 주입하기 위한 제1배관(131)과, 냉기실(123)로부터 냉기를 배출하기 위한 제2배관(132)을 포함할 수 있다. 이 때, 상기 제1배관(131)과 제2배관(132)은 냉기 주입의 정지시 역류하지 하지 않도록 체크밸브 형태로 구현할 수 있다. 편의상 제1배관(131)을 통해 냉기를 주입하고 제2배관(132)을 통해 냉기를 배출하는 모터 및 펌프 구성은 도면 도시를 생략한다.For example, as illustrated in FIG. 1, the cooling unit 130 may include a first pipe 131 for injecting cold air into the cold air chamber 123 and a second pipe for discharging cold air from the cold air chamber 123. 132 may include. At this time, the first pipe 131 and the second pipe 132 may be implemented in the form of a check valve so as not to back flow during the stop of cold air injection. For convenience, a motor and a pump configuration for injecting cold air through the first pipe 131 and discharging cold air through the second pipe 132 will be omitted.
따라서, 제1배관(131)을 통해 냉기를 주입하고, 제2배관(132)을 통해 냉기를 배출하여 냉기를 순환시키는 과정 동안 냉기의 대류 현상에 의해 외부 보호체(120) 내부의 태양전지셀 배열(110)의 온도를 낮추어 발전 효율을 향상 및 증대시킬 수 있게 된다.Therefore, during the process of injecting cold air through the first pipe 131 and discharging the cold air through the second pipe 132 to circulate the cold air, the solar cell inside the outer protector 120 is formed by convection of cold air. By lowering the temperature of the array 110 it is possible to improve and increase the power generation efficiency.
이와는 달리, 상기 냉각부(130)가 도 2 에 도시한 바와 같이, 상기 냉기실(123)의 냉기로부터 열을 빼앗아 외부로 방열하는 방열판(133)을 포함할 수 있다. 이 때, 상기 방열판(133)을 일방향 열전도성 특성을 가지도록 구현함에 의해 상기 외부 보호체(120) 내부의 태양전지셀 배열(110)에 의해 더워진 냉기로부터 방열판(133)이 열을 빼앗아 외부로 방열하게 되고, 이로 인해 외부 보호체(120) 내부의 태양전지셀 배열(110)의 온도가 낮아지게 되어 발전 효율을 향상 및 증대시킬 수 있게 된다.Alternatively, as shown in FIG. 2, the cooling unit 130 may include a heat dissipation plate 133 that takes heat from cold air of the cold air chamber 123 and radiates heat to the outside. At this time, the heat sink 133 takes heat away from the cold air heated by the solar cell array 110 inside the outer protector 120 by implementing the heat sink 133 to have a one-way thermal conductivity. As a result, the heat radiation of the solar cell array 110 inside the outer protector 120 is lowered, thereby improving and increasing power generation efficiency.

The thermoelectric element 134 absorbs the temperature of the cold air, the temperature of which is increased by the cell array 110, through the heat sink 133 of the cold chamber, so that the temperature of the solar cell array 110 inside the outer protector 120 is obtained.
