Several groups reported fabrication method of organic solar cells through a stamping technique by using PDMS mold. Although PDMS is a good stamp material, they have several problems in polymer transfer printing, especially when we use organic solvent (easily swollen). In this study, the polymer solar cells with an active layer of BHJ are successfully prepared via a simple imprinting transfer technique with help of UV-curable resin-coated polycarbonate (UV-PC) film. The transferred BHJ active layer from UV-PC film was perfectly retained at 220-nm thick on top of the PEDOT:PSS-coated ITO glass, and the device showed enhanced Jsc and device performance up to 3.19% after insertion of the TiOx interlayer between the active layer and Al cathode. This unique imprinting transfer can be considered as an alternative approach to replace the spin-coating when the matters, pre-coated layers are affected by the solvent for next layer.
