Title:

Japanese scientists build all-perovskite tandem solar cell with 30.2% efficiency

Detail:

The four-terminal tandem device relies on FAPbI₃ nanoparticles and a spectral splitting design, combining a 24.4% wide-bandgap top cell and a 21.5% narrow-bandgap bottom cell to reach 30.2% efficiency. The system improves light utilization by directing different wavelengths to optimized subcells.
