Abstract Scope |
The rapid advancement of carbon electrode-based perovskite solar cells (C-PSCs) presents challenges in efficiency, cost, and sustainability. This study addresses these challenges by enhancing device interfaces. Defective passivation of perovskite films, charge transport layers, and electrodes is identified as a critical issue.
Innovative fabrication methods, including annealing for the active layer and interfacial bridging techniques, are proposed. The annealing process of Cs0.17FA0.83Pb(I0.83Br0.17)3 under an air atmosphere achieves effective grain boundary self-passivation. Sustainability measures involve depositing a superhydrophobic layer and interfacial bridging with perovskite quantum dots, H2O2-treated TiO2, NaCl additive, FAI treatment, and polymer grafting, reducing defects and enhancing performance and stability of C-PSCs.
Additionally, a green-synthesized carbon quantum dots-based carbon paste electrode improves charge transfer. These findings enable the development of cost-effective, stable, and scalable C-PSCs suitable for indoor applications and nondestructive encapsulation, facilitating future eco-commercialization. |
