Luminescent solar concentrators for photovoltaic’s
Luminescent solar concentrators for photovoltaic’s – Erik van der Kolk
Earth Measured Physics , Sun, moon and planets Luminescence in the full moon night is magic. However, delving into the statues of the moon over the flat earth has not been easy. So, in the course of time, we have just understood something basilar. The moon moves on a cone very similar to that of the sun, only a little lower.
The polymer mounting medium acts to separate the dye molecules and prevent aggregation-induced quenching that reduces the QY. If the solvent or polymer mounting medium or the combination of both are poorly chosen, large clusters of the dye molecules will form which leads to visible nonuniformities. Moreover, if the solvent and polymer poorly paired, the mounting medium can separate from the solvent, resulting in wavy films with visible ripples that detrimentally affect the device aesthetic quality. Laser-cut Si photovoltaic cells are mounted around the two orthogonal edges and connected in parallel see Experimental Section for details. The second cyanine luminophore derivative Cy7.
Sunlight is absorbed by a luminescent material and re-emitted in all directions. A considerable fraction of the light is trapped in the plate, that acts as a light guide by total internal reflection like in a fiber optical cable and guided to the perimeter where solar cells convert it into electric power. In addition we make luminescent solar concentrators based on new concepts and test their efficiency. The more sunlight is absorbed the more power can be generated but the more colored the window becomes.
