Abstract

An organic solar cell based on onion carbon nanoparticle / Ag composite electrode and a preparation method thereof, belonging to the technical field of organic solar cell preparation. The invention synthesizes functional onion carbon nanoparticles with a layered structure through a simple hydrothermal method, uses its high charge collection ability to make onion carbon nanoparticles / Ag composite electrodes, and uses the electrodes to make polymer organic solar cell anodes . Onion carbon nanoparticles are composed of multi-layer sheet-like single-layer carbon molecules, which have a good charge storage effect. Due to the special layered structure of onion carbon nanoparticles, they can effectively realize charge collection and transmission, so they can effectively accelerate the charging of solar cells. collect. At the same time, due to the high light absorption characteristics of carbon materials, when the material receives light, the photoexcited electrons can effectively fill the interface trap between the silver electrode and the transport layer, so it can effectively improve the interface charge transport, thereby improving the energy of organic solar cells. conversion efficiency.

Description

technical field [0001] The invention belongs to the technical field of organic solar cell preparation, and in particular relates to an organic solar cell based on onion carbon nanoparticle / Ag composite electrode and a preparation method thereof. Background technique [0002] Polymer organic solar cells have been extensively studied in recent years due to their unique advantages of flexibility, low cost, and large-area production, and the current energy conversion efficiency has exceeded 10%. However, for polymer organic solar cells, high carrier recombination and low light absorption are problems that researchers must face. Carbon nanoparticle materials have attracted more and more attention from researchers in recent years because of their green, environmentally friendly and high-performance characteristics. Carbon nanoparticles with special structures synthesized by simple methods have also been applied in the field of solar cells, and have achieved certain results. Effec...
