Significant advancements in research have been made in recent years, with single-junction organic solar cells achieving efficiencies exceeding 20%. However, scaling up laboratory prototypes to large-area commercial modules remains challenging due to the absence of high-quality thin-film deposition techniques, particularly for ultra-thin interfacial layers. In here, we demonstrate a fully vacuum-processed approach utilizing InCl3 as hole-contact and C60/BCP as electron-contact interlayers, respectively, which guarantees dense and uniform charge transporting layers, while also ensuring consistent batch-to-batch reproducibility of module performance. In addition, such ultra-thin InCl3 layer significantly reduces the surface free energy of ITO substrates, thereby inhibiting the coffee ring effect during the active layer deposition, and obtaining a more homogeneous film in a large-scale size. As a result, we measured a power conversion efficiency of 16.5% (certified efficiency: 15.8%) under 1-sun illumination for the best-performing organic solar modules (aperture area = 15.6 cm2) with a geometric fill factor of 95.5%, making them highly completive amongst recently reported modules at similar size. Most importantly, our vacuum-processed interlayers exhibit excellent reproducibility and scale-up ability, paving a way to accelerate the industrialization of organic photovoltaic technology.
This study sought to assess the efficacy and mechanism of vacuum, ultrasonic, and combined ultrasonic-vacuum treatments (under N 2 protection) on the oxidative stability of Antarctic krill oil (AKO). Accelerated storage trials demonstrated that all three approaches significantly enhanced oxidation stability through oxygen removal (combined treatment > ultrasonic treatment > vacuum treatment). Comparative analysis demonstrated dehydrated AKO exhibited significantly higher oxidation stability but lower oxygen content and viscosity than hydrated counterparts (0.5 % water addition), and combined treatment's stabilizing effect was more pronounced in dehydrated AKO. Cryogenic scanning electron microscopy images suggested an increase in reverse micelle density upon water addition, and a decrease following combined treatment. This study indicates that water-formed reverse micelles in AKO compromise oxidative stability and attenuate deoxygenation efficiency, likely through increasing viscosity. This study firstly proposes that the combined treatment enhances AKO stability via a dual mechanism of direct oxygen removal and indirect reverse micelle influence.
