Regulation Strategy And Photovoltaic Performance Of Organic Conjugated Conductive Polymer

As we all know,the conjugated system of the organic conjugated polymer brings conductivity to the polymer itself,which is the basis for the application of the organic conductive polymer in the photovoltaic field.In this paper,based on the basic control method of organic conjugated conducting polymers,the effects of three basic regulation strategies on the photovoltaic performance of organic conjugated polymer were investigated: One-Dimensional Conjugated Regulation,Two-Dimensional Non-Fused Ring Conjugated Regulation and Fused Ring Conjugated Regulation.At the same time,the detailed photoelectric properties of polymer synthesized by different strategies were studied.The main contents are as follows:(1)From the perspective of the regulation strategy of one-dimensional conjugated system,the influence of heteroatoms was researched.In this paper,the photoelectric properties and photovoltaic properties of polyfluorinated polymer donor materials have been studied,aiming at the current popular design strategy of controlling the aggregation and energy level of PSCs materials by fluorine atom.(2)From the perspective of the regulation strategy of two-dimensional Non-Fused ring conjugated system,the effects of the introduction of 2D conjugated substituents on the side chains on the photoelectric properties and photovoltaic properties of polymers have been investigated.(3)From the perspective of the regulation strategy of fused ring conjugated system,the effects of changing the aromaticity and conjugation of the fused ring system on the photoelectric properties and photovoltaic properties of polymer materials have been studied.The stability of anti-aromatic conjugated materials was also explored.As a new type of photovoltaic cells which can partly replace high-cost inorganic silicon solar cells in the future,OSCs will play an irreplaceable role in the future for their outstanding characteristics such as simple manufacturing method,solution-processability and flexibility.This research on the basic control strategies of conductive polymers in this paper will bring important reference significance to the in-depth adjustment of key parameters such as the energy level and band gap of photovoltaic materials.
