We find that a fraction of electrons（holes）in the device are collected by anode（cathode）. The direction of the corresponding current is opposite to the direction of photocurrent. And the current density increases with the bias increasing but decreases as bimolecular recombination（BR）or geminate recombination（GR） intensity increases. The maximum power, short circuit current, and fill factor display a stronger dependence on GR than on BR. While the influences of GR and BR on open circuit voltage are about the same.Our studies shed a new light on the loss mechanism and may provide a new way of improving the efficiency of bulk heterojunction organic solar cells.展开更多

Methods Co-immunoprecipitation, GST pull-down and immunofluorescent assay were used to determine the combination of EBNA3C and Gemin3 and their combining domain. Stable EBNA3C knockdown cell lines were made by lentivirus-delivered small hairpin RNA and then puromycin selection. Western blot was used to check the effect of EBNA3C on Gemin3 expression. Results EBNA3C and Gemin3 combined with each other in vivo and in vitro through their C-terminals. EBNA3C up-regulated Gemin3 gene expression. Conclusion EBNA3C forms complex with Gemin3 and up-regulates its expression.展开更多
