Recently plasmonic effects have gained tremendous interest in solar cell research because they are deemed to be able to dramatically boost the efficiency of thin-film solar cells. However, despite of the intensive efforts, the desired broadband enhancement, which is critical for real device performance improvement, has yet been achieved with simple(More)
BACKGROUND The genetic basis of susceptibility to hepatocellular carcinoma (HCC) is poorly understood. Tumor necrosis factor alpha (TNF-α) is a cytokine that may act as an endogenous tumor promoter. The association between TNF-α 308 G/A polymorphism and HCC risk remains unclear. AIM The aim of this study was to investigate the association between TNF-α(More)
Crystalline silicon solar cells are predominant and occupying more than 89% of the global solar photovoltaic market. Despite the boom of the innovative solar technologies, few can provide a low-cost radical solution to dramatically boost the efficiency of crystalline silicon solar cells, which has reached plateau in the past ten years. Here, we present a(More)
Airborne vehicle tracking system is receiving increasing attention because of its high mobility and large surveillance scope. However, tracking multiple vehicles simultaneously on airborne platform is a challenging problem, owing to uncertain vehicle motion and visible frame-to-frame jitter caused by camera vibration. To address these problems, a new(More)
Implantable pumps have been used to prevent deep vein thrombosis and other diseases. In this article, we report for the first time the prevention and treatment of rethrombosis of the portal vein in liver transplantation with an implantable pump of the portal vein. Four hundred four orthotopic liver transplantation cases were retrospectively reviewed and(More)
The light intensity distribution inside organic solar cells is described by optical propagation matrix and the quantity of effective excitons is defined in this paper. The quantity of effective excitons describes the total intensity near the donor/acceptor interface, which can contribute to the generation of holes and electrons. The optimum structure then(More)
Using electrode buffer layer is one of effective ways to enhance electric performances of organic solar cells. And LiF is the widest materials, which is used as a cathode buffer layer. In this paper, small molecule organic solar cells based on ZnPc and C<inf>60</inf> are fabricated. And the LiF cathode buffer layer is studied. The mechanisms and functions(More)
