Molybdenum Disulfide Sees the Light #Robotics #AI

Molybdenum Disulfide Sees the Light #Robotics #AI

Roughly two years ago, researchers at MIT started to look at the potential of molybdenum disulfide (MoS2 ) for photovoltaic applications . The results were somewhat mixed. They saw relatively low conversion efficiency numbers, but were encouraged by the discovery that placing just three sheets of MoS2 into a one-nanometer-thick stack makes it possible to absorb up to 10 percent of incident sunlight. That’s an order of magnitude higher than gallium arsenide and silicon. While that was indeed an encouraging development, it was far from enough to make anyone start clamoring for MoS2 to replace silicon in photovoltaics or other photonics uses. Now researchers at Northwestern University have employed plasmonics in combination with MoS2, boosting its ability to absorb light as well as its photolumiscence. Applying plasmonic nanostructures to photovoltaics is not new. Back in 201...
