Silver Electrodes for Organic Solar Cells Printed via Laser‐Induced Forward Transfer
Laser‐induced forward transfer (LIFT) is presented as a new, contactless, and roll‐to‐roll compatible method for the deposition of silver top electrodes for organic solar cells (OSCs). Employing a nanosecond laser, highly reflective silver electrodes are printed by LIFT onto OSCs with P3HT:o‐IDTBR bulk heterojunction layers. Upon optimization of ink composition, source film thickness, and laser parameters, the resulting organic solar cells reach efficiencies of more than 5%, which are similar to those of reference devices with vapor‐deposited silver electrodes.
