한국의 기술, 태양광기술의 혁명 '박막형 태양광 판넬' Ultra-Thin Printed Solar Cells Could Turn on Lights for 1.3 Billion People

Ultra-Thin Printed Solar Cells Could Turn on Lights for 1.3 Billion People

아직도 어둠속에 빛의 혜택을 받지 못하는 13억명을 위한 희소식

태양광기술의 혁명 '박막형 태양광 판넬'

태양열 에너지 산업은 지속적 성장에 따라 보다 적은 비용으로 더 효율적인 성능을 요구한다.

이 박막 솔라셀은 탄소발자국(carbon footprint) 줄이고 싶어하는 저개발국가에 적합하며 진일보한 프린트형 솔라 셀 기술로 전세계 13억명에게 밝은 빛을 제공할 수 있을 것으로 전망하고 있다.

이 제품은 한국의 경인양행이 개발한 첨단 솔라셀 제품으로 이미 인도에서 시범 사용되어 우수한 사용 효율이 입증된 바 있다.

재질 또한 유리제품이 아닌 구리·인듐·갈륨·셀레늄(CIGS)로, 가볍고 얇아 쉽게 구부러지는 프린트형 솔라 셀 형태 제품이어서 굴곡이 심한 건물에도 쉽게 장착이 가능하다. 

무게는 기존 실리콘 타입의 솔라셀의 1/6정도에 불과해 설치비용이 절감되며 가정용 전기 3KW를 생산할 경우 6m x9m의 면적이면 가능하다.

As the solar energy trend continues to grow, it's becoming less expensive to produce. This is great for developed nations whose citizens want to decrease their carbon footprint, but it’s even better for those living in developing countries. Advances in printed solar cell technology are creating exciting possibilities for the 1.3 billion people who are still left in the dark.

The printed solar cells are paper-thin, flexible, and require only an industrial printer to manufacture. This makes them inexpensive and easy to transport to rural locales. “I’ve witnessed first-hand how the technology has enabled urban poor communities in India to access off-grid electricity,” says Scott Watkins of Korean firm Kyung-In Synthetic. “Its success is due to its cost effectiveness and simplicity. A 10×10 cm solar cell film is enough to generate as much as 10-50 watts per square meter.”

These cells have the potential to be an incredible tool in the fight against poverty. Like many developing technologies, however, there are still some kinks to work out. There’s a substantial capital investment that’s needed to acquire the industrial printer and replicate the production process. Additionally, the printed panels can be vulnerable to moisture which could lead to chemical contamination. Figuring out the solutions to these obstacles will be worth it, though, because the benefits to developing nations could be tremendous.
