Progress in Heterogeneous Nucleation-Induced Crystallization Strategies in Perovskite Solar Cells.
The performance of perovskite solar cells is fundamentally capped by the crystalline quality of perovskite active layers. Conventional solution-processing lacks kinetic control over nucleation, engendering granular heterogeneity, trap-state proliferation and halide phase segregation. Heterogeneous nucleation-induced cr...
