Korean scientists build mini perovskite solar module with 22.56% efficiency

GIST researchers have developed a perovskite mini-module with 22.56% efficiency by improving the SnO2 electron transport layer with PEI, reducing defects and electron loss. The module retained 94% of its performance after 500 hours, highlighting potential for scalable, stable perovskite solar cells and modules.A research team led by South Korea's Gwangju Institute of Science and Technology (GIST) has fabricated a mini perovksite module with an active area of 24.8 cm2 and a power conversion efficiency of 22.56%. The researchers explained that as the area of a solar cell or mini-module increases, ...
