Embodiment approach

[0020] see figure 1 , showing a schematic structural view of a first embodiment of a single-layer organic solar cell according to an embodiment of the present invention. In this embodiment, the single-layer organic solar cell includes a transparent insulating substrate 5, and a transparent anode electrode layer 4, a photosensitive layer 3, a metal nanoparticle layer 2, and a cathode electrode layer 1 sequentially stacked on the transparent insulating substrate 5. . Since the work function value of the metal nanoparticles in the metal nanoparticle layer 2 is lower than that of the cathode electrode layer 1, the cathode electrode layer 1 is chemically stable and difficult to be oxidized, while the metal nanoparticles in the metal nanoparticle layer are chemically stable. It is lively and easily oxidized. In this embodiment, the metal nanoparticle layer 2 is arranged between the photosensitive layer 3 and the cathode electrode layer 1, that is, the metal nanoparticle layer 2 is ...

Abstract

The invention discloses a single-layer organic solar cell, which comprises a transparent insulating substrate, and a transparent anode electrode layer, a photosensitive layer and a cathode electrode layer which are sequentially formed on the transparent insulating substrate in an overlapped manner; a metal nano-particle layer is formed on at least one surface of the cathode electrode layer in the overlapped manner; and the power function value of metal nano particles in the metal nano-particle layer is less than the power function value of the cathode electrode layer. The metal nano-particle layer is arranged in the single-layer organic solar cell, so a built-in electric field of a single-layer organic solar cell device is enhanced, the separation efficiency of right excitons is improved, and the energy transfer efficiency of the right excitons is finally enhanced; by a making method for the single-layer organic solar cell device, all the layers of the single-layer organic solar cell device are sequentially formed and tightly and firmly connected, so the single-layer organic solar cell device is stable in performance, high in production efficiency and applicable for industrialized production.

Description

technical field [0001] The invention belongs to the technical field of photoelectric conversion devices, and in particular relates to a single-layer organic solar cell and a preparation method thereof. Background technique [0002] A solar cell is a photovoltaic device that converts light energy into electricity. Since Bell Laboratories reported inorganic solar cells with an efficiency of 4% in 1954, solar cells have developed rapidly in the past half a century, and a "green energy revolution" has been set off worldwide. After the 1990s, photovoltaic devices such as gallium arsenide and cadmium telluride have been developed in the family of inorganic solar cells. However, until today, the high cost is the primary problem limiting the large-scale application of inorganic semiconductor solar cells. However, the cost problem is mainly caused by the inorganic materials themselves, so only the real low-cost green energy is an effective way to solve the energy problem. [0003]...
