Nanostructured Solar Cells
As a research fellow (MSCA-IF), Ishwor investigate the development of light-weight, flexible CIGS thin-film solar cell. By reducing growth temperature and understanding the phase transformation process of CIGS material, he fabricates high-quality CIGS thin-film solar cell on polymeric substrates using a single-step fabrication process – pulsed hybrid reactive magnetron sputtering. To boost the performance, a controlled amount of heavy alkali metals will be incorporated. These studies help to open a new frontier of solar business by fabricating solar cells on ultralight polymeric substrates. It is a promising technology that significantly lowers the production cost of the solar cell to be used in portable electronics, mobility application as well as in building integration, which is highly relevant in view of the European Strategic Energy Technology plan.
He received both Master and Ph.D. degrees from the Nagoya Institute of Technology (Japan). His PhD thesis was “Carbon Nanotubes towards Solar Cell Application”. As a research assistant, he worked at the Saitama University (Japan), where his work was focused on organic materials and carbon nanoparticles.
Ishwor joined the Tokyo University of Science (Japan) as project research in 2014, where he worked on CIGS thin-film solar cells. During the period, he received a grant as principal investigator for three years under the research category funding Grant-in-Aid for Early-Career Scientists from the Ministry of Education, Culture, Sports, Science and Technology (MEXT, Japan). His research focuses on the alkali-treatment on CIGS solar cells fabricated on glass and polyimide substrates. He has broad research and development experiences on various types of solar cells.
