[15p-A401-4] Grain Boundary Crystallization of Wide Band Gap Lead-Free Tin Perovskite by Surface Passivation
Keywords:solar cell, perovskite, wide bandgap
In order to fabricate tin-perovskite-silicon tandem solar cells, which are lead-free tandem solar cells, it is necessary to increase the efficiency of wide bandgap tin-perovskite solar cells with a band gap of 1.6-1.7 eV. In this study, we report on the increase in the curve factor of wide bandgap lead-free tin perovskite by the addition of silicon-based additives.
