Description
본 발명은 플렉시블 CIGS 박막 태양전지를 활용한 태양광 도로용 태양광 모듈에 관한 것으로서, 플렉시블 CIGS 박막 태양전지를 사용하여 도로의 표면을 태양광 설치를 위한 공간으로 활용하면서 설치되는 태양광 모듈의 고내구성 및 LED 광원을 내장함으로써 방향지시, 정보표시 등의 기능이 구현 가능하도록 하여 고기능성을 확보하는 것이 가능하도록 하는 것에 관한 것이다.The present invention relates to a photovoltaic module for a solar photovoltaic system utilizing a flexible CIGS thin film solar cell, and more particularly, to a photovoltaic module for a solar photovoltaic module using a flexible CIGS thin film solar cell, Durability, and LED light source, thereby making it possible to realize functions such as direction indication and information display, thereby ensuring high functionality.
일반적으로 기존의 태양광 발전은 일반부지(전, 답, 과수원, 목장용지, 임야) 및 유휴지, 건축물(BIPV, Rooftop), 수상 태양광 발전과 같은 양상으로 발전을 해왔다. Generally, conventional solar power generation has been developed in such aspects as general sites (front, answer, orchard, ranch, forest), idle land, buildings (BIPV, Rooftop), and water photovoltaic power generation.
이와 같이 일반 부지 및 유휴지에 태양광 설비를 설치를 하는 경우 태양광 발전 시스템이 설치되어 있는 동안은 기타 공간으로 활용을 하지 못하는 문제점이 있다. 건축물의 경우는 설치 시 하중에 대한 문제점을 고려하여야 하므로 설치비용의 증가가 발생을 하고 있으며 설치 후 관리 및 건물의 노후와 연계된 문제점이 발생되고 있다. 또한 수상 태양광 발전은 다양한 시도를 하고 있지만, 태풍에 대한 문제점 및 장기적인 내부식성 및 부력장치의 비싼 가격으로 인하여 설비투자에 대한 회수기간이 늦은 문제점이 발생하고 있다.In this way, when the solar power facility is installed in the general land and the idle land, there is a problem that it can not be utilized as other space while the solar power generation system is installed. In the case of buildings, the installation cost is increased due to the consideration of the load problem at the time of installation, and problems associated with post-installation management and the aging of the building are occurring. In addition, although water solar power generation is being tried variously, there is a problem that the recovery period for facility investment is late due to problems with typhoons and long-term corrosion resistance and high price of buoyancy devices.
이를 개선하기 위하여 도로 일체형 태양광 모듈 시스템 개발은 2009년도 개발이 시작이 되어 네덜란드에서부터 자전거 도로 100M 구간 시범운영을 실시한 것이 첫 사례이다. 초기 네덜란드는 2.5M*3.5M 크기의 콘크리트 모듈을 구성하여 상판에 1cm의 강화유리를 깔아서 오염방지 및 무거운 하중으로부터 태양광 전지를 보호해주는 기능을 구현하였다. 이후 연속적인 기술 개발을 해 나아가고 있다.In order to improve this, the development of integrated photovoltaic module system in the road was started in 2009 and it was the first case to carry out the pilot operation of 100M bicycle road from Netherlands. In the early days of the Netherlands, a concrete module of 2.5M * 3.5M was constructed, and 1cm of tempered glass was laid on the top plate to prevent pollution and protect the photovoltaic cell from heavy load. Since then, we have been developing continuous technology.
이러한 태양광 도로용 태양광 모듈은 설치 위치가 도로 등의 바닥에 설치되어 고내구성 및 정보의 표시와 같은 고기능성의 확보가 요구되고 있다.Such solar photovoltaic solar modules are installed at the bottom of a road or the like to ensure high durability and high functionality such as information display.
