Samenvatting:
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.
