    • Disclosed is a doped organic electroluminescent device, comprising the following structures laminated in succession: a conductive anode substrate, a hole injecting layer, a hole transportation layer, an electron barrier layer, a light-emitting layer, an electron transportation layer, an electron injecting layer and a cathode; and the material for the electron barrier layer is a hole transportation material doped with a cerium salt. The material for an electron barrier layer in such a doped organic electroluminescent device is a hole transportation material doped with a cerium salt which has a low work function of approximately −2.0 eV and can effectively block electrons. By doping the cerium salt having a low work function into the hole transportation material as the electron barrier layer, the LUMO energy level of the hole transportation material is greatly increased, thereby elevating the potential barrier between the electron barrier layer and the light-emitting layer, so that it is difficult for the electrons to transit to the side of the hole transportation layer and a good electron barrier effect is achieved. The present invention also provides a method for preparing the doped organic electroluminescent device.
    • 公开了一种掺杂有机电致发光器件,其包括以下结构:依次层压:导电阳极衬底,空穴注入层,空穴传输层,电子势垒层,发光层,电子传输层,电子注入 层和阴极; 并且用于电子阻挡层的材料是掺杂有铈盐的空穴传输材料。 这种掺杂的有机电致发光器件中的电子势垒层的材料是掺杂有铈盐的空穴传输材料,其具有大约-2.0eV的低功函数并且可以有效地阻挡电子。 通过将具有低功函数的铈盐作为电子阻挡层掺杂到空穴传输材料中,空穴传输材料的LUMO能级大大增加,从而提高电子势垒层和发光层之间的势垒 使得电子难以转移到空穴传输层的侧面并且实现良好的电子势垒效应。 本发明还提供了一种制备掺杂有机电致发光器件的方法。

    • The present invention relates to a polymer solar cell and a method for preparing the same. The cell comprises a conductive anode substrate, a hole buffer layer, an active polymer layer, an electron buffer layer and a cathode laminated in succession, wherein the hole buffer layer comprises a metal compound host and a guest doped in the metal compound host, the metal compound host being one selected from ZnO, ZnS and CdS and the doped gust being one selected from Li2CO3, Li2O, LiF, LiCl and LiBr. By doping a lithium compound with few electrons as a dopant into the metal compound host, a p-type doped layer facilitating the hole transportation is formed in the polymer solar cell. The dopant and the metal compound host have stable properties and would not corrode the conductive anode substrate, facilitating industrial production in the future and effectively improving the energy conversion efficiency of the polymer solar cell.

    • An organic electroluminescence device comprises the following structure: a conductive base (110), a hole injection layer (120), a light emission layer (140), and a cathode layer (170) are laminated in sequence. The material of the hole injection layer (120) comprises a conductive polymer and an azo initiator. A nano-network structure is provided on the connecting surface of the hole injection layer (120) and the light emission layer (140). After being heated to a higher temperature, the azo initiator can be decompounded to release N2, thus the nano-network structure is formed on the surface of the hole injection layer (120). The nano-network structure can efficiently increase the contacting area of the hole injection layer (120) and the adjacent layer. The injection efficiency of the hole is improved. A manufacturing method of the organic electroluminescence device is also provided.
