A solar cell with dimensions 12cm x 12cm is illuminated at standard test conditions. The cell presents the following external parameters:
Voc=0.8V,Isc=3A,Vmp=0.75V,Imp=2.5A
Calculate the fill factor (in %):
To calculate the fill factor, we can use the formula:
Fill Factor = (Vmp * Imp) / (Voc * Isc) * 100
Given:
Voc = 0.8V
Isc = 3A
Vmp = 0.75V
Imp = 2.5A
Substituting the values into the formula:
Fill Factor = (0.75V * 2.5A) / (0.8V * 3A) * 100
Fill Factor = 1.875W / 2.4W * 100
Fill Factor ≈ 78.125%
Therefore, the fill factor is approximately 78.125%.
To calculate the fill factor, we need to use the equation:
Fill Factor = (Vmp * Imp) / (Voc * Isc) * 100%
Given:
Voc = 0.8V (open-circuit voltage)
Isc = 3A (short-circuit current)
Vmp = 0.75V (voltage at maximum power point)
Imp = 2.5A (current at maximum power point)
Substituting these values into the equation:
Fill Factor = (0.75V * 2.5A) / (0.8V * 3A) * 100%
Let's solve this equation step by step to get the fill factor:
Step 1: Compute the numerator.
Numerator = 0.75V * 2.5A = 1.875W.
Step 2: Compute the denominator.
Denominator = 0.8V * 3A = 2.4W.
Step 3: Divide the numerator by the denominator.
Fraction = Numerator / Denominator = 1.875W / 2.4W = 0.78125.
Step 4: Multiply the fraction by 100% to get the fill factor.
Fill Factor = Fraction * 100% = 0.78125 * 100% = 78.125%.
Therefore, the fill factor of the solar cell is 78.125%.
