4.4 Solar cell parameters

\(\mathtt{\require{color}{\color[rgb]{0.000000000000000,0.500000000000000,0.500000000000000} SimSS}}\) will try to calculate the basic solar cell parameters (\(J_{sc}\), \(V_{oc}\), etc.) of the current-voltage characteristic it has calculated if the user is simulating something that could be a solar cell under illumination. So this is only done if there is a non-zero generation rate of carriers and if the work functions of the electrodes are different. The errors that are shown are solely based on the interpolation algorithm used, so they do not include the numerical accuracy of the actual simulation. The propagation of errors is included in, for example, calculating the maximum-power-point and the fill-factor. The parameters are shown on screen and stored in the \(\mathtt{\require{color}{\color[rgb]{0.000000000000000,0.500000000000000,0.500000000000000} scParsFile}}\). The program will compare the simulated solar cell parameters with the experimental ones if an experimental current-voltage curve was read (see \(\mathtt{\require{color}{\color[rgb]{0.000000000000000,0.500000000000000,0.500000000000000} useExpData}}\) and section 3.4). \(\mathtt{\require{color}{\color[rgb]{0.000000000000000,0.500000000000000,0.500000000000000} ZimT}}\) does not have this functionality.
