New solar-cell design based on dots and wires

March 27, 2013

MIT researchers improve efficiency of quantum-dot photovoltaic system by adding a forest of nanowires.


Scanning Electron Microscope images show an array of zinc-oxide nanowires (top) and a cross-section of a photovoltaic cell made from the nano wires, interspersed with quantum dots made of lead sulfide (dark areas). A layer of gold at the top (light band) and a layer of indium-tin-oxide at the bottom (lighter area) form the two electrodes of the solar cell. Images courtesy of Jean, et al/Advanced Materials
