A consortium led by Hanwha Q Cells, a leading manufacturer of photovoltaic solar cells in South Korea, has been selected for a three-year state project to develop and commercialize perovskite crystalline silicon solar cells with high durability and high efficiency by using tandem cell technology that builds 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 through each cell. Hanwha Q Cells said the consortium involving three private companies, two research bodies and three universities has signed an agreement with the state-run Korea Institute of Energy Technology Evaluation and Planning (KETEP) to develop module process technologies.

The project supervised by KETEP is aimed at securing South Korea's technological advantage over overseas competitors and promoting the commercialization of next-generation solar cell modules. The consortium will carry out research on technologies related to large-area modules.
