| 21. | In 1868 they noticed, in the solar spectrum, a bright yellow line which did not correspond to any substance then known.
|
| 22. | The Switching fluid in the greenhouse roof can be used as a filter for a certain part of the solar spectrum.
|
| 23. | He also made a series of elaborate measurements of the wavelengths of the solar spectrum by means of a large spectrometer.
|
| 24. | Therefore, O'Brien, as a physicist on staff, developed a carbon arcs with cored carbons that very closely matched the solar spectrum.
|
| 25. | AM1.5 solar spectrum, together with the maximum electricity conversion efficiency for every junction as a function of the wavelength . ]]
|
| 26. | First, the bandgap should be reduced to absorb red photons, which contain a significant fraction of the energy in the solar spectrum.
|
| 27. | It absorbs almost all the radiation in the visible portion of the solar spectrum and emits very little in the infrared range.
|
| 28. | In 1996 he created a solar spectrum environment for the Dwan Light Sanctuary at the United World College in Montezuma, New Mexico.
|
| 29. | Between 2003-08 he coordinated the " Fullspectrum " project for developing methods to make more efficient use of the full solar spectrum.
|
| 30. | These use a combination of several layers of gallium arsenide, indium gallium phosphide, and germanium to capture more energy from the solar spectrum.
