Sensitivity of solar-cell performance to atmospheric variables: I single cell. Technical report No. II-7
Measurements of the short-circuit current of a typical silicon solar cell under direct solar radiation were made for a range of turbidity, water vapor content, and air mass to determine the relation of the solar cell calibration value (current-to-intensity ratio) to those atmospheric variables. A modification of a previously developed regression equation was used to describe the relation between calibration value, turbidity, water vapor content, and air mass. Based on the value of the constants obtained by a least-squares fit of the data to the equation, it is found that turbidity lowers the value, while increase in water vapor increases the calibration value. Cell calibration values exhibited a change of about 6 percent over the range of atmospheric conditions experienced.
