Summary
| Description |
English: The limit for the maximum short-circuit current of a solar cell within the Shockley-Queisser model. The x-axis is the bandgap of the solar cell in electron volts, the y-axis is the highest possible short-circuit current density in mA/cm^2. This assumes that one electron is generated for every solar photon above the bandgap. The curve is wiggly because of IR absorption bands in the atmosphere: I used the actual AM1.5G solar spectrum data. I cross-checked my curve with an independently-calculated one and they agree to high accuracy, see Practical Handbook of Photovoltaics p128. The curve should be monotonically decreasing; the small upward bumps at low bandgap presumably come from rounding errors in the numerical integration. |

I did the calculation in Mathematica, plotted it in Origin, and did PDF-->SVG conversion in Inkscape. Then a few years later, I ported the code from Mathematica to Python, and you can now see the whole calculation and results at https://github.com/sbyrnes321/SolarCellEfficiencyLimits/blob/master/sq.ipynb
