What is the most common error when characterizing a solar cell?
The most common error when characterizing a solar cell is in the determination of the short-circuit current density (Jsc). Errors for experimental Voc are small because typically these voltages are of the order of mV which can be measured by modern instruments without much error.
What is the significance of solar cell measurement conditions?
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.
