Presented at: Symposium on the efficient use of solar radiation in photovoltaic power engineering, St. Petersburg, Russia, 3-4 november 2003.


Molecular-based concepts offer the potential of low materials and processing costs in photovoltaics (PV), which is especially interesting if high efficiencies can be obtained. To accomplish high efficiencies, a better utilization of the solar spectrum is of high importance. The concept of two-photon absorption in dye-sensitized solar cells and full spectrum aspects of luminescent flat plates concentrators are discussed in this paper. The two-photon dye cell can be compared to a tandem solar cell on the molecular level. The luminescent concentrator offers the potential to employ full spectrum utilization in combination with static concentration of both direct and diffuse light.
