Calibration procedures of a reference cell

In principal there are 4 different procedures to calibrate reference solar cells:

a) The direct sunlight method

b) The global sunlight method

c) The Differential spectral responsivity method

d) The solar simulator method

All 4 methods can be conducted as primary or as secondary calibration methods, dependent on the reference applied. A description of these 4 methods can be found in IEC standard 60904-4 [4]. Follow the links above to get briefly summarized descriptions.
