태양전지는 일반적으로 실리콘, 갈륨-비소, 구리-인듐-셀렌 등의 태양전지 소자를 상부 투명 보호재와 하부 기판 보호재로 보호하고, 태양전지 소자와 보호재를 접착제로 고정하여 제조되는 태양전지 모듈을 포함한다.Solar cells generally protect solar cell elements such as silicon, gallium-arsenide, copper-indium-selene with an upper transparent protective material and a lower substrate protective material, and include a solar cell module manufactured by fixing the solar cell element and the protective material with an adhesive. do.
태양전지 모듈에서 상부 보호재는 통상적으로 유리를 사용하는데, 유리는 태양광을 반사하기 때문에 태양전지 모듈의 발전 효율이 떨어지는 단점이 있다. In a solar cell module, the upper protective material generally uses glass, but since the glass reflects sunlight, there is a disadvantage in that the power generation efficiency of the solar cell module is lowered.
이를 해결하기 위하여 반사방지막을 사용하는 등의 다양한 연구가 수행되고 있다. In order to solve this problem, various studies such as the use of an anti-reflection film are being conducted.
