Dendrimers, new solar panel components
The solar panels that we can find on the market have two big problems: they are expensive and they are inefficient. The Lausanne Institute of Technology has used dendrimers to solve the second problem.
They are polymers branched by dendrimers. At the bifurcation, many of them acquire spherical shape and scientists claim that they are the ideal place for the implantation of intact molecules of solar panels.
Dyes are used in panels to absorb sunlight. By absorbing light, the electrons of the dyer are excited and, moved to the electrodes, electricity is obtained. Therefore, the more electrons are excited, the more electricity you get.
The spherical shape of these polymers considerably increases the surface on which dyes can be applied. Therefore, the amount of light absorbed at the same time is much higher and the effectiveness of the panels doubles.
However, the process of dendrimer synthesis is very complex and molecules are expensive. Dendrimer research is expected to apply to other cheaper materials.
