Photovoltaic Individual Conversion Steps Study in Poly-Si Silicon Solar Cell Under High Voltage Transmission Line

---

Résumé

This study addresses the insufficient understanding of the impact of high-voltage (HV) transmission line electric fields on photovoltaic (PV) conversion mechanisms, a critical issue for the deployment of PV systems in constrained land-use environments. Using a theoretical framework based on semiconductor physics and the Charge Simulation Method (CSM), we analyze the influence of external electric fields on the individual conversion processes of a polycrystalline silicon solar cell. Results show that the electric field enhances carrier kinetic energy, leading to increased current but reduced voltage near the HV line. A non-linear behavior of overall efficiency is observed, with a maximum at approximately 85m from a 225kV line. This work identifies an optimal installation zone (80-100m) and provides new insight into the coupling between external electric fields and PV conversion processes. These findings are relevant for optimizing PV deployment near transmission infrastructures.
