Shockley-read-hall recombination是什么

WebThe Shockley–Queisser limit gives the maximum possible efficiency of a single-junction solar cell under un-concentrated sunlight, as a function of the semiconductor band gap. If the band gap is too high, most daylight photons cannot be absorbed; if it is too low, then most photons have much more energy than necessary to excite electrons across the band … WebShockley Read Hall¶ class semiconductor.recombination.SRH (**kwargs) [source] ¶ This calculates the steady state shockley read hall recombiation that occurs for given defects. …
