A solar simulator is used to measure a 3-junction cell with area=0.27cm2. The simulator consists of 3 narrowband (laser) sources with the following wavelengths: 600 nm, 800nm and 1300nm. Assume the cells have band gaps of 0.67eV, 1.41eV and 1.88eV. What power is needed from each source to achieve a maximum Isc=1A

600 nm .................................. 0.67watts

800nm .................................. 1.41 watts

1300 nm ............................. 1.88 watts

Explanation:

the power needed by each source is evaluated below and check the attachment for better explanation.

600 nm .................................. 0.67watts

800nm .................................. 1.41 watts

1300 nm ............................. 1.88 watts
