Some basic considerations of measurements involving collimated direct sunlight. Technical report No. II-6. [For solar cell performance calibration]

Conference ·
OSTI ID:7214062

The geometry of collimators for devices or instruments dealing with terrestrial direct sunlight is discussed. Effects of the opening angle and slope angle of a collimator on the measurements are investigated with regard to variations of turbidity and air mass. Based on this investigation, geometric dimensions for collimators and certain realistic terrestrial reference conditions are recommended for the purpose of solar cell calibration in terrestrial applications.
