| Abstract | Solar energy has enormous potential. Yet, further technology improvements are needed to maximize its cost-effectiveness. Of all aspects that have been optimized in solar cell designs, the front electrode grid (see Fig.1) has received relatively little attention, although it plays an important role in the cell’s performance. Too wide electrode lines cause excessive shading, limi- ting power output. Likewise, too narrow or incorrectly distributed electrodes cause excessive resistive losses and suboptimal operating voltages. Electrode patterns thus directly impact the generated power, which strongly affects the cost-effectiveness of solar energy modules. TopSol will develop a systematic methodology to generate efficient electrode designs, using powerful topology optimization techniques. This involves multi-physical finite element modeling of nonlinear cell behavior, combined with iterative design updates. The required design resolution makes this computationally very intensive. TopSol will investigate innovative adaptive approaches to reduce computational costs while maintaining accuracy, ultimately enabling high-fidelity tailored solar cell electrode optimization. |
