Description

디스플레이 일체형 솔라셀 패널Integrated Display Panel
본 발명은 디스플레이 일체형 솔라셀 패널에 관한 것으로, 단결정 실리콘 태양전지 또는 CIGS 박막형 태양전지를 발전소자로 채택하여, 정보, 광고 등을 표현하는 디스플레이에서 소비하는 전력을 공급할 수 있도록 솔라셀과 디스플레이를 일체화한 디스플레이 일체형 솔라셀 패널에 관한 것이다.The present invention relates to a display integrated solar panel, which adopts a single crystal silicon solar cell or a CIGS thin film solar cell as a power generator, integrating a solar cell and a display to supply power consumed in a display representing information, advertisement, and the like. A display integrated solar panel.
최근 석유나 석탄과 같은 기존 에너지 자원의 고갈이 예상되면서 이들을 대체할 대체 에너지에 대한 관심이 높아지고 있다. 그 중에서도 태양전지는 반도체의 성질을 이용하여 빛 에너지를 전기에너지로 변환하는 장치로서 다른 신재생 에너지원에 비하여 그 에너지원을 장소에 구애받지 않고 사용할 수 있다는 장점이 있다.Recently, with the anticipation of depletion of existing energy sources such as oil and coal, there is increasing interest in alternative energy to replace them. Among them, the solar cell is a device that converts light energy into electrical energy using the properties of a semiconductor, and has the advantage that the energy source can be used regardless of the place, compared to other renewable energy sources.
태양전지의 구조 및 원리에 대해서 간단히 설명하면, 태양전지는 P(Positive)형 반도체와 N(Negative)형 반도체를 접합시킨 PN 접합 구조를 하고 있Briefly describing the structure and principle of the solar cell, the solar cell has a PN junction structure in which a P (positive) type semiconductor and an N (Negative) type semiconductor are bonded to each other.
으며, 이러한 구조의 태양전지에 태양광이 입사되면, 입사된 태양광이 가지고 있는 에너지에 의해 상기 반도체 내에서 정공(Hole)과 전자(Electron)가 발생하고, 이때, PN접합에서 발생한 전기장에 의해서 상기 정공(+)는 P형 반도체쪽으로 이동하고 상기 전자(-)는 N형 반도체쪽으로 이동하게 되어 전위가 발생하게 됨으로써 전력을 생산할 수 있게 된다.When solar light is incident on a solar cell having such a structure, holes and electrons are generated in the semiconductor by the energy of the incident sunlight, and at this time, an electric field generated by the PN junction The holes (+) are moved toward the P-type semiconductor and the electrons (-) are moved to the N-type semiconductor, thereby generating electric potential, thereby generating power.
특히, 광흡수층으로 실리콘을 사용하는 태양전지는 결정질 기판형 태양전지와, 비정질의 박막형 태양전지로 구분된다.In particular, solar cells using silicon as the light absorption layer are classified into crystalline substrate type solar cells and amorphous thin film type solar cells.
근래에는 다양한 산업분야에서 엘이디를 응용한 다양한 제품이 개발되어 적용되고 있는데, 특히 고휘도의 엘이디 램프는 수명이 반영구적이면서도 소비전력이 매우 낮은 장점이 있으므로, 기존의 형광등이나 백열등, 나트륨등 및 수은등을 비롯한 다양한 전등을 대체할 수 있다.In recent years, various products using LEDs have been developed and applied in various industrial fields. In particular, high brightness LED lamps have the advantages of being semi-permanent and having very low power consumption. Can replace various lights.
즉, LED 램프를 통해 각종 유해물질이 포함되고 수명이 짧은 기존의 전등을 대체함에 따라 환경오염을 줄일 수 있는 효과가 있음과 더불어, LED 램프의 낮은 전력소모를 통해 에너지 절감 효과도 얻을 수 있을 뿐만 아니라, 광소자의 종류에 따라 적색, 녹색, 청색의 광 출력을 얻을 수 있어, 광통신을 비롯하여 전자광고판 등에 문자나 숫자 등의 영상을 표시하는데 많이 이용되고 있다.In other words, the LED lamp contains various harmful substances and replaces the existing lamps with short lifespan, which can reduce environmental pollution. In addition, energy saving effect can be obtained through low power consumption of the LED lamp. In addition, red, green, and blue light outputs can be obtained depending on the type of optical device, and are widely used for displaying images such as letters and numbers in optical communication and electronic billboards.
또한, 문자나 숫자 등의 영상을 여러 가지 색상으로 표시하기 위해서 서로 다른 색(빛의 3원색)의 엘이디 칩들을 근접 배치함으로써 색의 간섭을 통해 자연의 색을 표현하도록 하고 있다.In addition, in order to display images such as letters and numbers in various colors, LED chips of different colors (three primary colors of light) are disposed close to each other to express natural colors through color interference.
