Material design approach improves solar cell efficiency

The correlated electron "metal" SrRuO3 exhibits strong visible slight absorption. Overlaid here on the AM1.5G solar spectrum, it can be seen that SrRuO3 absorbs more than 75 times more light than TiO2. The structural, chemical, and electronic compatibility of TiO2 and SrRuO3 further enables the fabrication of heterojunctions with exciting photovoltaic and photocatalytic response driven by hot-carrier injection. Lane Martin, University of Illinois.

Development method allows researchers to more efficiently utilize the solar spectrum.

Real advance in quantum dot photovoltaics from MIT

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.

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