Korea East-West Power and Ulsan National Institute of Science and Technology (UNIST) have jointly launched a project to develop an ultra-high efficiency multi-junction solar cell using perovskite.

The company announced that researchers from the two organizations held the first meeting at its head office in Ulsan and discussed the technology of producing a standard cell (15.6×15.6 square centimeters)-sized large-scale solar panel by establishing a vacuum deposition semiconductor facility.

The development of a vacuum deposition-based ultra-high efficiency silicon and perovskite tandem solar cell is intended to raise the efficiency of a solar cell from 19% to 22% by stacking perovskite and silicon semiconductors in multi layers.
