Efficiency of carbon-based perovskite solar cells significantly improves with dual passivation of the crystal lattice and grain boundaries.
A notable increase in power conversion efficiency to 21.5% showcases the effectiveness of the dual passivation method.
Observational analysis shows the enhancements in solar cell performance led to substantial decreases in charge recombination.
These findings highlight the potential for dual passivation techniques in advancing solar cell technology, with further exploration needed for commercial applications.
