Who: Massachusetts Institute of Technology, USA.
What: A method to greatly increase the efficiency of ZnO/PbS quantum dot solar cells. By engineering the band alignment of the quantum dot layers through the use of different ligand treatments, a certified efficiency of 8.55% has been reached. See “Improved performance and stability in quantum dot solar cells through band alignment engineering”
Where: Photovoltaics.
When: Commercialization is likely to be more than 5 years away as the efficiencies are still comparably low.
