Continued improvement to the efficiency of solar cells depends critically on a better understanding of their optical and electrical characteristics. Traditional light sources for this task include broadband lamps and light emitting diodes, which are difficult to match accurately to solar spectra and cannot be focused tightly for microscopic studies. Recently, solar simulators based on super-continuum lasers have demonstrated arbitrary and accurate spectral shaping and the ability to be focused to spots of diameter approaching 1 micrometer. Preliminary studies of solar cells made of crystalline silicon, amorphous silicon, thin films, III-V semiconductors, and multi-junctions have all shown promising results. Research proposals are being sought that would advance our preliminary work on conventional cells, as well as proposals to initiate new measurement science for emerging, third-generation solar cell technologies. Proposals to achieve sub-wavelength, plasmonic, broadband focusing for the selective illumination of nanostructures are of particular interest. New efforts in application areas such as bio-photonics are also encouraged.
