Keywords: ShockleyQueisserJSC.svg en 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 own Sbyrnes321 2011-02-08 The data-file for this graph is freely available ask me at http //en wikipedia org/wiki/User_talk Sbyrnes321 I did the calculation in Mathematica the plotting in Origin and the PDF-->SVG conversion in Inkscape The Mathematica source code is posted on my website http //sjbyrnes com/ Photovoltaic power schemas and diagrams Solar cell schemas and diagrams
