Korea East-West Power Co. 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, which is a next-generation solar cell material.
The company announced on March 12 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 percent to 22 percent by stacking perovskite and silicon semiconductors in multi layers. This technology makes maximum use of the solar light that is not converted to electric power by the conventional single silicon solar cells.
Perovskite is a metal oxide with a special structure that has properties of an insulator, semiconductor, and conductor. It has recently emerged as a next generation solar cell material.
