Roll-to-Roll Inkjet Printing and Photonic Sintering of Electrodes for ITO Free Polymer Solar Cell Modules and Facile Product Integration

Small polymer solar cell modules that are manufactured without indium‐tin‐oxide using only roll‐to‐roll printing and coating techniques under ambient conditions enable facile integration into a simple demonstrator (for example a laser pointer). Semitransparent front electrode grid structures prepared by roll‐to‐roll inkjet printing in conjunction with photonic sintering enable preparation of complete modules on flexible substrates and subsequent integration of the modules into a laser pointer demonstrator.
