Embodiment Construction

[0011] The technical solutions of the present invention will be described in further detail below in conjunction with specific embodiments.

[0012] Preparation method of photovoltaic material comprising acceptor-type thienopyridine copolymer, which will give acceptor-type thienopyridine copolymer 60%; SnO 2 5%; 2% silane coupling agent, 8% cuprous sulfide, and 25% dichloromethane are mixed and heated to 450 degrees Celsius within 30 minutes and kept at 450 degrees Celsius for 1 hour. Percentages are mass percentages. The donor-acceptor type thiophene pyridine copolymer is 3-hexylthiophene- co -pyridine copolymer, the preparation process is as follows: 2,5-dibromo-3-hexylthiophene and 2,5-dibromopyridine are used as raw materials, and 1,3-bis(diphenylphosphine)propane nickel dichloride is used as Catalyst, adopts Grignard reagent method to synthesize 3-hexylthiophene- co - pyridine copolymers. After keeping at 400-500 degrees Celsius for 1-2 hours, it is applied to the sur...

Abstract

The invention belongs to the field of photovoltaic materials, and particularly relates to a preparing method of a photovoltaic material comprising a donor-acceptor type thiophene-pyridine copolymer. The method includes mixing 50-60% of the donor-acceptor type thiophene-pyridine copolymer, 1-10% of SnO2, 1-2% of a silane coupling agent, 5-10% of cuprous sulfide and 20-40% of dichloromethane, heating to 400-500 DEG C, and maintaining the temperature at 400-500 DEG C for 1-2 h, with the percentages being mass percentages. The photovoltaic material contains metals and the copolymer and is high in light conversion efficiency.

Description

technical field [0001] The invention belongs to the field of photovoltaic materials, and in particular relates to a method for preparing a photovoltaic material comprising a donor-acceptor type thienopyridine copolymer. Background technique [0002] Existing photovoltaic materials are generally in the form of copolymers or metal complexes, but there are no materials containing both metals and copolymers. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned problems, and provide a method for preparing a photovoltaic material containing both metal and copolymer and having a high light energy conversion rate and containing a donor-acceptor type thienopyridine copolymer. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a method for preparing a photovoltaic material comprising a donor-acceptor type thienopyridine copolymer, which is characterized in that it includes t...
