Abstract

Abstract : High efficiency and bendable organic solar cells were fabricated using Ag nanomesh/ZnO hybrid transparent electrodes. Abstract : We demonstrate a facile approach to fabricate Ag nanomesh transparent conducting electrodes (TCEs) on a flexible substrate using nanoimprint lithography (NIL) and transfer printing without a conducting polymer. The Ag nanomesh TCEs exhibited a high transmittance of ∼88% and a low sheet resistance of ∼15 Ω sq −1 as well as superior mechanical flexibility. Furthermore, flexible inverted organic solar cells (IOSCs) with Ag nanomesh TCEs exhibited a power conversion efficiency (PCE) of ∼7.15% under 100 mW cm −2 AM 1.5G illumination as well as superior long-term stability under ambient conditions. This type of highly flexible and transparent Ag nanomesh electrode is a promising candidate for use with TCEs in various optoelectronic devices.
