However, coating sequential layers can be<br \/>\nhindered 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 postless 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.<\/p>\n<div><span class=\"NLM_string-name\">Pratik Sen<\/span>,\u00a0<span class=\"NLM_string-name\">Yuan Xiong<\/span>,\u00a0<span class=\"NLM_string-name\">Qianqian Zhang<\/span>,\u00a0<span class=\"NLM_string-name\">Sungjune Park<\/span>,\u00a0<span class=\"NLM_string-name\">Wei You<\/span>,\u00a0<span class=\"NLM_string-name\">Harald Ade<\/span>,\u00a0<span class=\"NLM_string-name\">Michael W.
