Efficient Tin-Germanium Perovskite Solar Cell Breakthrough

• Malaysian researchers achieve up to 31.49% efficiency with tin-germanium perovskite solar cell, paving the way for improved stability and performance.

Researchers from Malaysia have developed a tin-germanium-based perovskite solar cell with a potential efficiency of up to 31.49%. By integrating tin and germanium as mixed B cations in the perovskite absorber, they were able to achieve an efficiency ranging from 24.25% to 31.49% by modulating the perovskite layer thickness.

The use of mixed cations in the perovskite absorber has the potential to improve stability, light absorption, and charge carrier mobility. By incorporating both tin and germanium in the B cation, the researchers were able to reduce defects and increase cell performance. Simulations showed that varying the thickness of the perovskite layer resulted in different efficiencies, with a 6,000 nm-thick absorber achieving an efficiency of 31.73%. The researchers plan to further validate their models and refine their parameters for future research.
