Buried-Interface Regulation of Crystallization and Charge Extraction in Perovskite Solar Cells.
In n-i-p perovskite solar cells, the SnO2/perovskite buried interface plays a decisive role in governing crystallization and charge extraction. Here, trisodium methylglycine diacetate (MGDA) is introduced onto SnO2 to regulate precursor behavior during crystallization. Molecular-dynamics simulations using PbI2∙DMSO as...
