Comparative Analysis of Edge Soiling Resilience: Full-Cell vs. Half-Cell Photovoltaic Modules in Different Mounting Orientations

Figure 2

Schematics and characteristic curves of the standard 60-full-cell module and 120-half-cell module. (a, b) Schematic views of the full-cell and half-cell modules in portrait mounting orientation, respectively. Each module contains three black dots, which represent the bypass diodes strategically positioned to divide the cells into three (full-cell module) or six (half-cell module) relatively independent substrings, as indicated by the green dotted boxes. The orange arrows indicate the current directions and the polarity of each cell within the modules. (c, d) Characteristic curves of the 60-full-cell module and the 120-half-cell module, respectively. The solid line represents experimental results while the dots represent simulated results. (e, f) The I-V curves of a substring with (e)/without (f) a bypass diode for the shaded cell.
