High‐Performance Intrinsically Stretchable Organic Photovoltaics Enabled by Robust Silver Nanowires/S‐PH1000 Hybrid Transparent Electrodes

Abstract Intrinsically stretchable organic photovoltaics ( is ‐OPVs) hold significant promise for integration into self‐powered wearable electronics. However, their potential is hindered by the lack of sufficient consistency between optoelectronic and mechanical properties. This is primarily due to the limited availability of stretchable transparent electrodes (STEs) that possess both high conductivity and stretchability. Here, a hybrid STE with exceptional conductivity, stretchability, and thermal stability is presented. Specifically, STEs are composed of the modified PH1000 (referred to as S‐PH1000) and silver nanowires (AgNWs). The S‐PH1000 endows the STE with good stretchability and smoothens the surface, while the AgNWs enhance the charge transport. The resulting hybrid STEs enable is ‐OPVs to a remarkable power conversion efficiency (PCE) of 16.32%, positioning them among the top‐performing is ‐OPVs. With 10% elastomer, the devices retain 82% of the initial PCE after 500 cycles at 20% strain. Additionally, OPVs equipped with these STEs exhibit superior thermal stability compared to those using indium tin oxide electrodes, maintaining 75% of the initial PCE after annealing at 85 °C for 390 h. The findings underscore the suitability of the designed hybrid electrodes for efficient and stable is ‐OPVs, offering a promising avenue for the future application of OPVs.
