Summary
| Description |
English: 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.
Русский: Черная линия — предел максимального напряжения холостого хода солнечного элемента в модели Шокли — Кейсера. По оси X отложена запрещенная зона солнечного элемента в электрон-вольтах, по оси Y — максимально возможное напряжение холостого хода в вольтах. Красная пунктирная линия — «y=x», проведена для иллюстрации, что напряжение холостого хода всегда несколько меньше напряжения запрещенной зоны. |

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
