A consortium of academic research teams and private companies led by Hanwha Q Cells, a major photovoltaic manufacturer in South Korea, was selected for a state project to commercialize tandem perovskite silicon solar cells.

In an effort to widen the technology gap with China, South Korean companies and researchers have tried to develop new solar energy technologies like tandem cells that build perovskite on top of silicon solar cells. Tandem solar cells can be individual cells or connected in series, which are simpler to fabricate but the current is the same though each cell.

For South Korea's state project to develop next-generation solar cell technologies and get ahead of Chinese companies in the global market, the consortium led by Hanwha Q Cells aims to secure and commercialize original technologies for basic materials.

"We will also secure leading technologies in the next generation of solar energy to enhance our competitiveness in the global solar energy market," said Hanwha Q Cells CEO Kim Hee-cheul.
