Bottom Passivation of Sn-Pb Perovskites Using Ethylenediamine-Phosphonic Acids for Efficient HTL-Free Solar Cells
{{output}}
Tin-lead (Sn-Pb) perovskite solar cells are promising for tandem applications but face challenges with Sn2+ oxidation and defect-induced recombination, particularly with conventional hole transport layers (HTLs). We introduce ethylenediamine tetramethylphospho... ...
