Air-Stable All-Inorganic Nanocrystal Solar Cells Processed from Solution

by Ilan Gur et al. Science, 21 Oct 2005 We introduce an ultrathin donor-acceptor solar cell composed entirely of inorganic nanocrystals spin-cast from solution. These devices are stable in air, and post-fabrication processing allows for power conversion efficiencies approaching 3% in initial tests. This demonstration elucidates a class of photovoltaic devices with potential for stable, low-cost power generation. Read more
