| description | The geometric configuration of grid electrodes critically determines both the photovoltaic (PV) conversion efficiency and grid volume for solar cells. This paper presents an optimization methodology employing width-varying quadratic curves to parameterize grid electrode profiles, coupled with a comprehensive power loss model. A genetic algorithm (GA) is implemented to minimize total power loss, systematically optimizing grid designs for solar cells with 156 × 156 mm², 182 × 182 mm², and 210 × 210 mm². Compared to conventional equal-width 2-busbar configurations, the optimized quadratic-curve grid electrodes demonstrate significant improvements: conversion efficiency enhancements of 1.45 %, 1.63 %, and 1.77 % with simultaneous grid volume reductions of 11.44 %, 11.39 %, and 11.23 %, respectively. For 12-busbar architectures, more pronounced benefits were achieved, with efficiency gains reaching 4.71 %, 5.33 %, 5.87 % and remarkable volume reductions of 46.55 %, 49.42 %, 51.51 % across all cell sizes. These findings offer a possible route for improving both performance and reducing grid volume. |
