Hanwha Q CELLS Recruits Next-Generation Solar Experts to Accelerate R&D...

Hanwha Solutions is focusing on research and development by recruiting external experts to lead the development of next-generation solar technology.

Hanwha Solutions Q CELLS division recently appointed Dr. Moon Su-jin, formerly of the Swiss Center for Electronics and Microtechnology (CSEM), as an executive. Dr. Moon has been conducting research and development for mass production of 'Perovskite-Crystalline Silicon Tandem (heterojunction) cells,' which enhance the light absorption rate and power generation efficiency of solar cells using perovskite.

Perovskite-silicon tandem cells are manufactured by placing a highly electrically conductive perovskite cell on top of a silicon cell, allowing them to absorb wavelengths of light that conventional single silicon cells cannot, resulting in higher potential power generation efficiency.

To efficiently utilize limited space for renewable energy production, it is necessary to increase solar power generation efficiency and output. However, conventional silicon cells have reached practical limits in power generation efficiency. Tandem cells can achieve significantly higher power generation efficiency, making them a promising next-generation solar cell technology.

Dr. Moon has over 10 years of experience researching solar cells using perovskite, with a background in developing both tandem cells and single perovskite materials. She also worked as a postdoctoral researcher in the laboratory of Professor Michael Gr?tzel, a leading authority in solar cell technology.

At Q CELLS, Dr. Moon is expected to be responsible for overall tasks related to mass production, including research on perovskite formation, maximizing tandem cell efficiency, optimizing equipment and processes for pilot production lines, and strengthening synergy between the upper cell and lower cell R&D organizations.
