Solar Cells; High-quality perovskite materials developed capable of utilizing long-wavelength sunlight

Scientists have developed the world’s first method to fabricate high-quality perovskite materials capable of utilizing long-wavelength sunlight of 800 nm or longer. Compared to conventional methods, this method enables the creation of perovskite materials that have a 40-nm wider optical absorption spectrum, a high short-circuit current and high open-circuit voltage. Thus, this method is regarded as a new approach to enhance the efficiency of perovskite solar cells.
