Abstract

The invention discloses a polymer solar cell with a novel structure and a manufacturing method of the polymer solar cell, which belong to the technical field of a solar cell. An electric collecting layer of the polymer solar cell is divided into two layers; a first electric collecting layer is a two-dimensional plane film covered on a transparent electric base plate; a second electric collecting layer is arranged on the first electron collecting layer; and the second electric collecting layer is a film with a one-dimensional nanometer array structure. The manufacturing method for the second electric collecting layer comprises but is not limited to a solvothermal method, a template method, an electro-deposition method, an anodic oxidation method and the like. According to the polymer solar cell, the film with the one-dimensional nanometer array structure grows on the two-dimensional plane film to be as an electric collecting material; and the polymer solar cell has the advantage in long-term stability of photoelectric property of the battery compared with the traditional structure, is specially beneficial to the separation of load and directionality for transmission of the separated load and can effectively improve light current density and photoelectric conversion efficiency of the battery.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a polymer solar cell with a novel structure and a preparation method thereof. Background technique [0002] Polymer solar cells are also called organic solar cells. Organic polymers are easy to process, cheap, and have the characteristics of being able to make large-area flexible devices. Polymer solar cells made of organic conjugated polymers have all-solid-state characteristics and are easy to prepare, and the size, shape and surface properties of the nanostructures can be adjusted by chemical methods, which has great potential application value. Polymer solar cells are currently one of the hot spots in solar cell research. [0003] However, due to the limitation of the charge separation mechanism and load transmission distance of polymer solar cells, polymer solar cells generally use a double-penetrating structure called a bulk heterojunction composed of organic conjugat...
