162:Предел Шокли — Квиссера (предел детального баланса, предел эффективности Шокли — Квиссера) — максимальная теоретическая эффективностью солнечного элемента, использующего одиночный p-n переход для сбора энергии, где единственный механизм потерь — излучательная рекомбинация в солнечном элементе. Впервые предел был рассчитан Уильямом Шокли и Хансом-Йоахимом Квиссером из компании Shockley Semiconductor в 1961 году, что дало максимальную эффективность 30 % при энергии фотонов 1,1 эВ. Это ограничение является одним из самых фундаментальных в производстве солнечной

some other assumptions too.) The curve is wiggly because of IR absorption bands in the atmosphere: I used the actual AM1.5G solar spectrum data. Sometimes people approximate the solar spectrum by a 6000K blackbody spectrum instead, and they get a smoother curve with slightly different values. I cross-checked my curve with independently-calculated ones and they agree to high accuracy,

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
