| Keywords: ShockleyQueisserVOC.svg en Black curve The limit for the maximum open-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 open-circuit voltage in volts The red dotted line is y x showing that the open-circuit voltage is always somewhat smaller than the bandgap voltage The model assumes a single-junction solar cell under unconcentrated light and some other assumptions too I used the AM1 5G solar spectrum data for the calculation I cross-checked my curve with an independently-calculated one and they agree to high accuracy see Practical Handbook of Photovoltaics p129 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 | ||||
