Luminescent solar concentrators transfer

Practical aspects of the energy transfer described here may be found in increasing the pumping efficiency of glass lasers or in recently studied luminescent solar concentrators (Reisfeld and j0rgensen, 1982 Reisfeld et al., 1981, 1983b Kisilev et al., 1982 Reisfeld and Kisilev, 1985). 

A practical disadvantage of the sensitized planar electrodes described in the previous section was their low solar energy conversion efficiencies. An experimental drawback was that characterization was limited to photoelectrochemical or luminescence techniques. Both of these issues arose from the poor light harvesting by monolayers on flat surfaces or inefficient interfacial electron transfer yields from thick films or concentrated solutions. In 1990, Gratzel and co-workers reported experimental studies of dye sensitized colloidal Ti02 films that eliminated both of these problematic issues [112]. The effective surface area for sensitizer binding...
