Chasing clues about the infant universe in relic light known as the cosmic microwave background, or CMB, scientists are devising more elaborate and ultrasensitive detector arrays to measure the properties of this light with increasing precision. To meet the high demand for these detectors that will drive next-generation CMB experiments, and for similar detectors to…
On the Way to Multiband Solar Cells
When visiting California’s central valley in the summertime, it’s hard to imagine that solar energy isn’t single-handedly meeting the west coast’s energy needs. But one problem with modern solar cells is that while the solar spectrum covers a wide range of energies they can only harness light of a single energy,. This means that very…
