Polymer photovoltaic material

Abstract

The invention relates to a conjugated polymeric material in optoelectronic materials, in particular to a polymer photolectric material which is characterized in that: the molecular structure is showed as the right formula, wherein, R1 represents a unit connected with a main chain through double bond and of alkyl, benzene, thiophene or pyrrole structure; R2 represents one of butyl, hexyl or capryl; and n represents the repetition number of the main chain unit of the polymer and is a natural number more than or equal to 4. The polymer photolectric material can improve the absorption and utilization ratio of solar radiation, can be applied to the optical activity layer of polymer solar batteries combined by high molecular material during the preparation of photoelectric functional devices toprepare polymer solar batteries and can be applied to the luminescent layer of polymer electroluminescent devices combined by high molecular material to prepare polymer electroluminescent white lightdevices.

Description

A polymer optoelectronic material technical field The invention relates to a conjugated polymer material in an optoelectronic material, in particular to a polymer optoelectronic material. Background technique Conjugated polymers, including polythiophene and its derivatives (PTs), polyparaphenylene vinylene and its derivatives (PPVs), polyparaphenylene and its derivatives (PPPs), and polymers of heterocyclic aromatic hydrocarbons, have certain Photoactive, so it has been widely used in the field of optoelectronics. In order to improve the optoelectronic properties of these materials, many methods have been used to modify them. Although some progress has been made in these research works, the performance of optoelectronic materials still needs to be improved in practical applications. In the application field of polymer solar cells, due to the problem of low absorption and utilization of solar radiation energy, the energy conversion efficiency of polymer solar cells is lo...
