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

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

wavelength divides in half and speed stays the same.
