A research team led by Professor Kim Han-ki of the Department of New Materials Engineering has developed a transparent cathode manufacturing technology to implement the next generation translucent perovskite solar cell.
The translucent perovskite solar cell is highly efficient and is expected to be applicable to building integrated photovoltics (BIPV), the next generation of building external glass, or automotive glass. However, due to the limitations of transparent electrode casod technology, only laboratory-level research has been reported so far.
Professor Kim Han-ki's research team developed a technology that can manufacture translucent perovskite solar cells without plasma damage using linear face target sputtering (LFTS) technology used in mass-production of semiconductors and displays.
※ Sputter technology: A device that produces thin films when manufacturing semiconductors/displays
※ Plasma Damage: A phenomenon in which semiconductor devices, displays, or solar cells are damaged due to exposure to plasma.
Although ITO electrode technology using existing sputter technology had to increase process temperature as well as plasma damage, the research team developed a technology that can successfully produce high-efficiency translucent perovskite by applying InZnSnO and LFTS technology that show transparent electrode characteristics at room temperature.
※ ITO Electrode Technology: In order to produce a display/solar cell, transparent and electrical electrodes are required, and indium Tin Oxide (ITO) substances are generally used.
※ InZnSnO: Unstructured transparent electrode material produced by doping Zn (zinc) and Sn (comment) to In2O3 oxide semiconductors at the same time
Professor Kim Han-ki said, "This study will be a key technology in producing translucent perovskite solar cells in the future, and it is meaningful that domestic researchers have secured key technologies for implementing translucent perovskite solar cells."
This study was conducted with the support of KEPCO's external tasks and joint research with the Korea Electric Power Research Institute, and the findings were published online in January 2021 in the international journal Nano Energy.
