Consider a c-Si solar cell whose fingers have a resistance R=10ohms. Which would be the finger´s resistance (in ohms) if the finger´s width is doubled and the finger´s height is one third of its initial value
double width, height 1/3?
cross sectional area is not 2/3 of the original, so resistance is now 3/2 * 10 ohms or 15 ohms
