Perovskite solar cells offer unique opportunities for tandem solar cell applications due to their bandgap tuning capabilities. The introduction of cyanate as a bromide substitute has shown promising results in enhancing the efficiency of perovskite solar cells. Through significant lattice distortion and improved defect formation energy, the OCN-based perovskite exhibits reduced nonradiative recombination, resulting in a high-efficiency triple-junction solar cell with stable performance.
