The stability of perovskite solar cells (PSCs) has been considered as one the major obstacles toward practical application. Defects in layer and ion infiltration from hole transport (HTL) can trigger degradation n-i-p PSCs. Herein, phenylhydrazine-4-sulfonic acid (PHPA) was employed an additive to modulate crystallization during film formation, enlarging crystal grain sizes ∼3 μm. Density functional theory (DFT) calculations revealed that PHPA could effectively inhibit formation iodine vacancies (VI) passivate under-coordinated Pb2+ ions. Additionally, perfluorooctanoic (PFOA) adopted surface located dangling defects, improve hydrophobicity, Li+ migration HTL bottom perovskite, thus enhancing device's environmental operational stability. Consequently, resulting devices delivered a champion efficiency 25.1% with excellent maximum-power-point (MPP) tracking

Dye-sensitized solar cells (DSSCs) based on the TiO2 photoanode are promising contenders for photovoltaic technology. However, shows severe charge recombination and leads to rapid photodegradation of absorbed dyes due its photocatalytic activity. Herein, we developed a hybrid by embedding multifunctional fulleropyrrolidine (PCBO-3) into film. The film presents higher electron mobility, aligned energy level with dyes, reduced oxygen vacancy defects, synergistically contributing suppressed Moreover, dye molecules can form hydrogen bonds PCBO-3 molecules, thus enhancing loading photon harvesting. resulting DSSCs yield efficiencies 11.6% under standard one sun illumination 32.8% 1500 lx dim light, representing highest values Z907-based DSSCs. encapsulated devices show enhanced long-term operational stability, retaining 76.8% 89.3% initial PCE light 500 h, respectively. In contrast, only 48.9% 69.5% their original efficiency could be maintained control devices. Our results suggest that anode is facile approach revitalizing
