The Shockley–Queisser limit for the efficiency of a solar cell, without concentration of solar radiation. The curve is wiggly because of absorption bands in the atmosphere. In the original paper, [1] the solar spectrum was approximated by a smooth curve, the 6000K blackbody spectrum. As a result, the efficiency graph was smooth and the values ...
Speed 2: Cruise Control is a 1997 American action thriller film produced and directed by Jan de Bont, and written by Randall McCormick and Jeff Nathanson.It is the sequel to Speed (1994) and stars Sandra Bullock (reprising her role from the original film), Jason Patric and Willem Dafoe.
The numbers are normally not similar as you suggest. But in any case, f c cannot be more than 1, and the upper limit (the Shockley-Queisser limit) requires taking f c = 1. Eric Kvaalen 19:05, 6 September 2016 (UTC) Yes, virtually all above-gap photons come from recombination, but not all recombinations create above-bandgap photons.
English: The Shockley-Queisser limit for the maximum possible efficiency of a solar cell. The x-axis is the bandgap of the solar cell, the y-axis is the highest possible efficiency (ratio of electrical power output to light power input).
Third-generation photovoltaic cells are solar cells that are potentially able to overcome the Shockley–Queisser limit of 31–41% power efficiency for single bandgap solar cells. This includes a range of alternatives to cells made of semiconducting p-n junctions ("first generation") and thin film cells ("second generation").
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 ...
