【Abstract】 In this work,the poly(2,6’-4,8-bis((2-ethylhexyl)-thiophene-5-yl)Benzo[1,2-b;3,3-b]dithiophene-alt-[ Chemicalbook1,3-bis-(5-yl)-thiophene)-5,7-bis-(2-ethylhexyl)Benzo[1,2-c: 4,5-c’] dithiophene-4,8-dione](PBDB-T) and 3,9-bis(2-methylene-(3-(1,1-dicyanomethyl)-indanone)-5,5,11,11-tetra(4-hexylphenyl)-DITHIOPHENE [2,-d: 2’,3’-d’]-S-INDENE [1,2-b:5,6-b’] dithiophene(ITIC) were used as polymer donor and non-fullerene receptor. The photoelectric conversion efficiency of the cell was improved through optimizing the preparation process of the active layer by controlling the spin coating speed,concentration of the active layer solution and the ratio of donor to acceptor. The efficiency of the device was increased by 10.67% by optimizing the preparation process of the active layer.更多还原
