A research team, affiliated with UNIST introduced highly flexible and transparent solar cells by punching micro-holes in silicon. This breakthrough has been led by Professor Choi Kyeongjin and his research team in the Department of Materials Science and Engineering at UNIST.
In this study, the research team demonstrated colorful transparent silicon photovoltaics with an unprecedented level of color control and enhanced flexibility by successfully filing those silicon holes with organic dyes. The concept of transparent solar cells (TSCs) has attracted much attention, as they can be installed on the windows and exterior walls of a building, while also adding aesthetic beauty to the buildings.
The findings of this research have been published in the online version of ‘Advanced Functional Materials, ahead of publication on November 17, 2021. This study has been supported through the Mid-career Researcher Program and the Nano Future Material Source Technology Development Program through the National Research Foundation of Korea.
