The efficiency of Photovoltaic cells in unfiltered sunlight

New page

==The efficiency of Photovoltaic cells in unfiltered sunlight==
The best efficiency for photovoltaic cells in sunlight filtered through the atmosphere is for a band gap of about 1.25 eV as shown on the [https://en.wikipedia.org/wiki/Solar_cell_efficiency#mediaviewer/File:ShockleyQueisserFullCurve.svg|Wikipedia graph]. It is also shown on the graph that User 2014 128.156.10.80 referenced in his edit of 4 March 2014. Clearly these graphs refer to the spectrum of sunlight filtered through Earth's atmosphere, with AMO and AM1.5 being standard approximations of the spectrum of sunlight filtered through Earth's atmosphere. The 6000K blackbody spectrum is another approximation of this filtered sunlight, closer to sunlight filtered through the atmosphere than it is to unfiltered sunlight in cislunar space. So these references do not support the contention that "ilmenite photovoltaic cells would have a worse conversion efficiency then silicon or gallium arsenide in unfiltered solar radiation." The statement in ''THE MOON, Resources, Future Development, and Settlement'' by Schrunk et al. on page 273 should still be taken as indicating that ilmenite photovoltaic cells would have a better conversion efficiency then silicon or gallium arsenide in unfiltered solar radiation. So, I will revert the edit by User 2014 128.156.10.80. - [[User:Farred|Farred]] 23:29, 30 August 2014 (BST)
