More energy fromsunlight strikes the Earth in one hour (4.3•1020J) than all the energy consumed on the planet in a year (4.1•1020J). There is a huge gap between our present use of solar energy and its enormous undeveloped potential. This defines a grand challenge in energy research.
Twenty terrawatts of electrical power could be generated by covering just 0.16 percent of the earth’s surface with solar cells with 10 percent efficiency.

The research in Prof. Lioz Etgar's group focuses on the development of radically new nanostructures and molecular materials for the production of innovative solar cells, third generation solar cells.

We concentrate on functional materials for solar energy application and the assembly and the characterization of the solar cell.

Recently our work was highlighted at:

And in the 10 top cited papers on photovoltaic solar cells from 2012.

- Hybrid approaches for the synthesis of the nanostructures, such as colloidal
synthesis and chemical bath deposition.

- Novel self-assembly (e.g. layer-by-layer) techniques and low cost deposition
and patterning processes. (e.g. spin coating, ink jet)

- Optical characterization of the nanostructures materials.

- Photovoltaic characterization using Solar simulator, Incident photon to current efficiency (IPCE), electrical
