London: An innovative 3D solar-cell design with a radically different architecture which drives down the costs of cell manufacture may define the future of renewable energy as it potentially reduces optical losses within a device, according to UK scientists.
The scientists at the University of Sheffield and energy technology company Power Roll in the UK have demonstrated how a unique architecture based on a surface embossed with micro-grooves could also make solar power more efficient.

혁신적인 3D 태양전지, "재생 에너지의 미래가 될 수 있을 것" 런던: 혁신적인 3D 태양전지 설계로, 전지 제조 비용을 절감하는 아키텍처가 장치 내에서 광학적 손실을 잠재적으로 감소시킴으로써 재생 에너지의 미래를 정의할 수 있다고 영국의 과학자들은 말한다. 영국 셰필드 대학과 에너지 기술 회사인 파워롤의 과학자들은 마이크로 홈으로 양각된 표면에 기초한 독특한 건축물이 어떻게 태양 에너지를 더 효율적으로 만들 수 있는지를 보여주었다. 혁신적인 3D 디자인은 기존의 PV(광전극) 모듈이 요구하는 많은 제조 공정 단계를 제거하고 보통 태양 전지에 적합하지 않은 새로운 재료를 사용할 수 있게 한다. "저탄소 녹색 전기를 만들기 위해 태양전지를 사용하는 것에 세계적인 관심이 있다. 이 연구를 이끈 데이비드 리지 셰필드대 물리천문학부 교수는 "뒤로 접촉한 태양열 모듈의 디자인은 혁신적이고 우아하며 기기 내에서 광학적 손실을 잠재적으로 줄일 수 있다"고 말했다. 황기철 콘페이퍼 에디터 큐레이터 Ki Cheol Hwang, conpaper editor, curator |

The innovative 3D design removes many of the manufacturing process steps required by existing photovoltaics (PV) modules and allows new materials to be used that would not usually be appropriate in regular solar cells.
"There is global interest in using solar cells to generate low carbon, green electricity. The design of the back contacted solar module is both innovative and elegant, and can potentially reduce optical losses within the device," said professor David Lidzey from the Department of Physics and Astronomy at the University of Sheffield, who led the research.
"The devices we have demonstrated have a promising efficiency, whereby seven per cent of sunlight power falling onto a single photovoltaic micro-groove device is directly converted to electrical power, this is already around a third of what the best performing but expensive solar cells produce today," Lidzey said.
Power Roll predicts that solar modules produced using this design will weigh only a fraction of an equivalent-power conventional solar module which could benefit less developed and off grid areas of the world where it is not viable to transport heavy solar panels as well as a wide range of other applications.
Researchers said other benefits of the design include removal of expensive transparent conductive oxides, the use of simple and low cost electrical interconnections and the ability to tune electrical output to match user requirements.

"Over the last 40 years, the majority of solar cells have been based on a conventional flat structure, in which layers of different materials are deposited one upon another to create the solar cell," said Trevor McArdle, Senior Research Scientist at Power Roll.
"However, we have developed a radically different architecture to make solar cells using a surface patterned by micro-grooves that individually are a fraction of the width of a human hair, McArdle said.
The study was published in the journal Energy and Environmental Science.
"We believe that our patented architecture is a game changer. The market opportunities for our solar PV product are significant, including off-grid solutions, commercial and domestic systems, powering the internet of things, portable power generation and military applications. This technology will deliver significant economic and social benefits to end users," said Neil Spann, CEO of Power Roll.
