Two Ag-based metal organic complexes (<bold>HA1</bold>and<bold>HA2</bold>) are employed as a new class of dopant-free HTMs for the application in PSCs. The cell based on<bold>HA1</bold>achieved high PCE 11.98% under air conditions, which is comparable to employing doped spiro-MeOTAD (12.27%) same conditions.
