On the left-hand side of the figure below a III-V triple junction solar cell is shown. On the right-hand side, the J-V curves of the individual component cells and the multi-junction solar cell are shown. Which junction corresponds to sub cell 3?
a.
cell based on Ge
A) sub cell based on Ge
To determine which junction corresponds to sub cell 3 in the figure, follow these steps:
1. Examine the J-V curves of the individual component cells and the multi-junction solar cell on the right-hand side of the figure.
2. Look for the curve that corresponds to the highest energy conversion efficiency or the highest output voltage.
3. Identify the curve that has the highest voltage at the same current density as the other curves intersecting it.
4. This highest voltage corresponds to the sub cell with the highest energy conversion efficiency in the multi-junction solar cell, which is sub cell 3.
By following these steps and analyzing the J-V curves, you can determine which junction corresponds to sub cell 3 in the figure.
To determine which junction corresponds to sub cell 3 in the figure, we need to understand the layout of the triple junction solar cell and the J-V curves.
1. First, locate sub cell 3 in the figure. It should be mentioned or marked somehow, perhaps with a label or number.
2. Once you have identified sub cell 3, look at the J-V curves on the right-hand side of the figure. Each curve represents the current-voltage characteristics of a specific sub cell or component cell.
3. Compare the J-V curve of sub cell 3 with the J-V curves shown. Observe the shape and behavior of the curve, such as the current and voltage values at different points.
4. Look for similarities or consistent trends between the J-V curve of sub cell 3 and any of the given J-V curves. Pay attention to the curve's shape, the magnitude of the current and voltage, and any notable features.
5. Once you have identified the J-V curve that matches the behavior of sub cell 3, determine which junction it corresponds to. Each J-V curve represents a specific junction within the triple junction solar cell (e.g., junction 1, junction 2, junction 3).
By following these steps, you will be able to identify which junction corresponds to sub cell 3 in the given figure.
