-type contact. As shown in the visualization below, the potential energy gradient reduces the likelihood of carrier trapping at the grain boundaries.
The simulation results (Figure 1) demonstrate that a 0.4 eV gradient across the layer leads to a 25% improvement in the Fill Factor (FF) compared to a uniform bandgap. 5. Conclusion

The graded bandgap structure effectively "funnels" electrons toward the -type contact
Below is a complete, original research paper draft focusing on a high-interest 2026 physics topic: . This topic bridges fundamental physics (solid-state, optics) and modern technological application.
We model the charge carrier dynamics using the drift-diffusion equations. The efficiency of a solar cell is governed by the continuity equation for electrons ( ) and holes ( is the recombination rate (loss)
) to create a built-in electric field, facilitating carrier extraction before recombination occurs. 4. Results and Discussion
