SOLUTION PROCESSED HIGH PERFORMANCE TRANSPARENT ORGANIC PHOTOVOLTAIC CELLS

FP7-NMP-2013-SMALL-7 > | Grant agreement ID: 604506 

November 2013 – October 2016

Organic photovoltaic (OPV) technology is the only means of producing semi-transparent colourless cells providing a clear and undistorted image when looking through at device. It can be perfectly integrated in buildings facades, offering an enormous potential for electricity production units to penetrate urban areas.

Bisazides as crosslinkers for absorber polymers/fullerene layer OPV active layers

To achieve optimal light harvesting in a solution-processed semi-transparent OPV cell, the SOLPROCEL consortium proposed to combine complementary know-how in three of the fundamental aspects of OPV technology: nano-fabrication (FAU), light management (ICFO), and organic synthesis (FhG-IAP). The quantifiable goal of SOLPROCEL was to obtain the materials needed for fully solution-processed high performance transparent OPV cells and to raise the efficiency of such cells from 5.6% to 9%, this later value corresponding to 80% of the 12% efficiency of the corresponding opaque cell. Thus, the SOLPROCEL project aimed to develop light-weight, flexible, semi-transparent OPV that exhibit sensitivity to low light levels and can be processed in a roll-to-roll application.

Within this project, SPECIFIC POLYMERS developed low refractive-index UV-crosslinkable thin layers and bisazides crosslinking agents for the stabilization of the polymer-fullerene absorber layer. Low-RI UV-crosslinkable layers exhibiting a refractive index of 1.34 were built from the three fluoro-acrylate monomers. Bisazides crosslinking agents enabled crosslinking of the absorber polymers/fullerene layer OPV active layers by reaction between azide groups and double bonds.
