Abstract: The present invention relates to an organic solar cell for a current-voltage test and a preparation method thereof. The disclosed organic solar cell for the current-voltage test comprises a substrate with a preset ITO pattern, wherein ITO on the substrate with the preset ITO pattern is used as the anode layer, and a hole transport layer, an active layer, an electron transport layer and a cathode layer are stacked successively to form a solar cell. A plurality of cell positions are designed on the substrate in the present invention. Each cell has an independent cathode test site and an anode test site. The distance between the test site of each cell and the cell is kept the same and the distance is short enough; and the cells are distributed evenly on the substrate discretely. The present invention has high substrate utilization rate, high data accuracy and good parallelism.

Abstract: The present invention is directed to a novel synthetic method for producing nanoscale heterostructures, and particularly nanoscale heterostructure particles, rods and sheets, that comprise a metal core and a monocrystalline semiconductor shell with substantial lattice mismatches between them. More specifically, the invention concerns the use of controlled soft acid-base coordination reactions between molecular complexes and colloidal nanostructures to drive the nanoscale monocrystalline growth of the semiconductor shell with a lattice structure incommensurate with that of the core. The invention also relates to more complex hybrid core-shell structures that exhibit azimuthal and radial nano-tailoring of structures. The invention is additionally directed to the use of such compositions in semiconductor devices.
