The efficiency of a solar cell can decisively be increased by a
surface structuring process. A novel laser based technology to
structure organic solar cells has proved itself as a very fast
and efficient process and is thus very promising for industrial
applications. |The direct laser beam interference pattering
method (DLIP) transfers nanostructures in one step into metals,
ceramics or In recent years the photoelectric efficiency of
organic photovoltaics has made enormous progress. The technology
offers the scaling potential to large and flexible photovoltaic
substrates. Further efficiency improvements are expected from
optimizing the intrinsic properties of the organic material.
Micro- and nanostructured surfaces are very advantageous for
organic solar cells since they increase the optical path length
for the incoming light within the active material. The
scientists at the Fraunhofer IWS apply a very fast and efficient
technology with short processing times at increased resolutions,
the so-called direct las
