“We apply luminescence imaging as tool for the nondestructive visualization of degradation processes within bulk
heterojunction polymer solar cells. The imaging technique is based on luminescence detection with a highly sensitive silicon charge-coupled-device AZD8931 camera and is able to visualize with time advancing degradation patterns of polymer solar cells. The devices investigated have been aged under defined conditions and were characterized periodically with current-voltage (I-V) sweeps. This allows determining the time evolution of the photovoltaic parameters and-in combination with the luminescence images-understanding differences in the observed degradation behavior. The versatile usability of the method is demonstrated in a correlation between local reduction of lateral luminescence and a fast decrease of the short-circuit current (I(sc)) due to the loss of active area. Differences in the degradation of photovoltaic parameters under varied aging conditions are discussed. (C) 2011 American Institute of Physics. [doi:10.1063/1.3553864]“
the presumably first intentional ABO-incompatible deceaseddonor kidney and pancreas transplantation with a severe antibody-mediated rejection during a rebound of isoagglutinins. Rejection was successfully treated with eculizumab, which inhibits the terminal pathway of complement. Complement OICR-9429 in vitro analysis (C3, C3d, g, and a modified assay of classical complement-related hemolytic function) documented complement
activation and confirmed that eculizumab completely blocked complement function. At 6 months, the patient had normal kidney and pancreas function, and histological evaluations revealed no evidence of sustained graft damage. This successful transplantation suggests that ABO barriers can safely be overcome without extensive preconditioning, when the complement inhibitor eculizumab is included.”
“Surface passivation has become an essential factor for translating high-efficiency crystalline silicon solar cell concepts into industrial Caspase inhibition production schemes. In photovoltaics, a widespread method to determine the surface recombination is to measure the effective charge carrier lifetime from the photoconductance of symmetrically passivated silicon wafers in transient or quasi-static mode. In this work, it is shown how the injection history at the surface influences the transient effective lifetime measurement for several passivation layers. This dependence leads to systematic differences between quasi-static and transient measurements. The influence can be explained by charge trapping in slow surface states at the surface passivation layer.
