Korea Electric Power Corp. (KEPCO) recently stated that it has developed a flat-type perovskite solar cell with "the world's best photoelectric conversion efficiency".

KEPRI, an R&D subsidiary of KEPCO, reportedly succeeded in producing perovskite solar cell with 20.4% photoelectric conversion efficiency, surpassing the 20.1% efficiency of flat solar cells announced so far.

"Perovskite solar cells will be easily installed and will be attached to portable electronic devices in the future," said a KEPRI official, adding, "We will make more efforts to improve efficiency in order to commercialize perovskite solar cells in the future and contribute to strengthening the competitiveness of the renewable energy industry in Korea."
