Abstract: Laser power-over-fiber (LPoF) technology is one of the crucial means to energize the monitoring sensor nodes for electrical equipment in high-voltage environment. The optimization of metal front contacts grid architecture for laser photovoltaic (PV) converters is crucial to the improvement and application of LPoF technology. Numerical simulation and optimization of metal grid architecture for PV converters is presented with application to devices of relatively small size. The model is constructed based on the open source Solcore library written in Python, and a three-step-process is developed to create a hybrid quasi-3D model for PV converters. In this paper, given different layer architectures of GaAs-based single-junction PV converters, numerical simulation is run to study how the photoelectric conversion efficiency is affected by the base thickness and the metal grid architecture under different illumination profiles. The results show that with the help of the model, the metal grid architecture can be optimized to yield the highest conversion efficiency under different layer architecture and illumination profiles. The model and optimization results can be used to guide the development of laser PV converters.

Key words: laser photovoltaic converter, laser power-over-fiber, metal grid optimization, numerical simulation, hybrid quasi-3D model, photoelectric conversion efficiency
