AB  - Polymer conductors that are solution-processable provide an opportunity to 
      realize low-cost organic electronics. However, coating sequential layers can be 
      hindered by poor surface wetting or dissolution of underlying layers. This has 
      led to the use of transfer printing where solid film inks are transferred from a 
      donor substrate to partially fabricated devices using a stamp. This approach 
      typically requires favorable adhesion differences between the stamp, ink, and 
      receiving substrate. Here, we present a shear-assisted organic printing (SHARP) 
      technique that employs a shear load on a post-less polydimethylsiloxane (PDMS) 
      elastomer stamp to print large-area polymer films that can overcome large 
      unfavorable adhesion differences between the stamp and receiving substrate. We 
      explore the limits of this process by transfer printing 
      poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) films with 
      varied formulation that tune the adhesive fracture energy. Using this platform, 
      we show that the SHARP process is able to overcome a 10-fold unfavorable adhesion 
      differential without the use of a patterned PDMS stamp, enabling large-area 
      printing. The SHARP approach is then used to print PEDOT:PSS films in the 
      fabrication of high-performance semitransparent organic solar cells.
