Three main measuring systems are required for the calibration of solar cells: one to determine the active area, another to determine the spectral responsivity, and a third one to measure the I–V characteristics.
The significance of the measurement conditions is analyzed by evaluating the prediction of the later module performance by solar cell measurements. The notation proposed to the Solar Cell Efficiency Tables distinguishes different options for front and rear contacting as well as different chuck reflectance.
The notation proposed to the Solar Cell Efficiency Tables distinguishes different options for front and rear contacting as well as different chuck reflectance. In the following, the notation is briefly introduced and then explained on typical measurement configurations.
To evaluate the significance of the solar cell measurement conditions, the prediction of the module performance by solar cell measurements has been evaluated.
To fully characterize the measurement conditions, the notation should be supplemented by the busbar widths and solder pad dimensions, the front and rear grid resistances as well as the spectral bifaciality of the solar cell in the long-wavelength regime. This is not feasible though.
High solar cell efficiencies are then measured at the cost of low CTM P values. Inappropriate solar cell measurement conditions can thus result in the overestimation of module performance when the CTM P losses due to interconnection of the solar cells in the module layout are not considered.
