Summary
[edit]DescriptionShockleyQueisserBreakdown2-ru.svg |
English: The Shockley-Queisser limit for the maximum possible efficiency of a solar cell (black), and the inevitable losses that limit it (other colors). The black height is energy that can be extracted as useful electrical power; the pink height is energy of below-bandgap photons; the green height is energy lost when hot photogenerated electrons and holes relax to the band edges; the blue height is energy lost in the tradeoff between low radiative recombination versus high operating voltage. The curves are all wiggly because of IR absorption bands in the atmosphere: I used the actual AM1.5G solar spectrum data. I cross-checked the black curve with independently-calculated ones and they agree to high accuracy, [1] [2]. The other curves besides the black curve are not published in exactly this form to my knowledge, but it's a straightforward part of the same calculation.
Русский: Предел Шокли — Кейссера максимально возможного КПД солнечного элемента (черный) и неизбежные потери, которые его ограничивают (другие цвета). Высота чёрной зоны — это энергия, которую можно извлечь в виде электроэнергии; розовая — энергия фотонов ниже запрещенной зоны; зеленая высота — это потеря энергии при релаксации горячих фотогенерированных электронов и дырок на краях запрещённой зоны; синяя — это энергия, потерянная в результате компромисса между низкой рекомбинацией с излучением и высоким рабочим напряжением. Все кривые волнистые из-за полос поглощения в атмосфере. |
