The model is a single cell from a solar panel (Figure 1). The cell consists of a pair of aluminum electrodes covering a silicon cell. The top electrode is a thin tapered body, and has an electric potential of 0.6V. The bottom electrode is a flat rectangle, acting as ground. The analysis focuses on determining the voltage drop across the silicon cell, and along the tapered end of the front electrode (figure 2). The electric field and the current density are the main analysis points.
