...newly discovered “black silicon” is created through a laser treatment inside a chamber filled with sulfur gases—a procedure that allows silicon to absorb a larger fraction of the solar spectrum, according to Meng-Ju Sher, a physics research assistant...
Black silicon has practical applications, such as cameras and night vision goggles, but Kenneth C. Hammond ’12—who works in Mazur’s lab—hopes to create more efficient solar cells with the new substance...
Though regular silicon does “a fairly good job” of absorbing the solar spectrum, black silicon is able to absorb a much greater percentage, and Hammond said researchers hypothesize that black silicon could create a more efficient solar cell...
...only somewhat less-frightening version of “2012” would involve the end of history arriving with no earthquakes, solar flares, or eruption of mountains in national parks. Instead, the end of history in this epic would arrive incrementally, as societal changes saturate the public sphere with freedom.
