11. The shift in the solar spectrum , and related spectral shift effects from 1880 to 1960 ). 12. In the process, he recorded a solar spectrum consisting of 3, 000 absorption lines in the optical band. 13. Atomic absorption lines are observed in the solar spectrum and referred to as Fraunhofer lines after their discoverer. 14. Some MgH spectral lines show up prominently in the second solar spectrum , that is the fractional linear polarization. 15. The solar spectrum and to solar activity such as solar flares and coronal mass ejections ( CMEs ). 16. 3 . " The Extraterrestrial Solar Spectrum " A . J Drummond and M . P . Thekaekara, Eds. 17. In this way TPVs can overcome a fundamental challenge for traditional PVs, making efficient use of the entire solar spectrum . 18. The third component, a secondary p-type donor polymer, acts to absorb light in a different region of the solar spectrum . 19. In 1886, Lippmann's interest turned to a method of fixing the colours of the solar spectrum on a photographic plate. 20. In 1886 Lippmann's interest had turned to a method of fixing the colors of the solar spectrum on a photographic plate.
