Peripheral group effects on the photophysical and photovoltaic properties of bulk-heterojunction type solar cells based on star-shaped conjugate molecules with triphenylamine core

Herein we have investigated the photovoltaic properties of ferrocenyl tetracyanobutadiene derivatives of diketopyrrolopyrroles SM1 and SM2 as efficient non-fullerene acceptors along with a donor–acceptor (D–A) conjugated polymer P as a donor for polymer solar cells.

Four solution-processable D-A-D structured organic molecules with diketopyrrolopyrrole (DPP) as acceptor unit and triphenylamine (TPA) or (4-hexyl)thieno [3,2-b]thiophene (HTT) as donor unit, DPP8-TPA, DPP8-TPA-OR, DPP6-HTT and DPP8-HTT, were designed and synthesized for the application as donor materials in solution-processed organic solar cells (OSCs). The molecules show broad absorption and relatively lower highest occupied molecular orbital energy levels. Photovoltaic properties of the molecules were investigated by fabricating the bulk-heterojunction OSCs with the molecules as donor and PC 71 BM as acceptor. Power conversion efficiency of the OSC based on DPP8-HTT reached 1.5% under the illumination of AM1.5, 100 mW cm −2 .

Homo And Lumo

In this paper, wepresent new organics chemical structures of pendant phenyl ester-substituted thiophene and benzothiadiazole based copolymers leading to donor (D)-acceptor (A) structure-types. Geometrics and photo-physical properties of the studied chemical structure are exploited in the further ground and excited-state. Theoretically, using the DFT and TD-DFT quantum chemical calculation implanted in Gaussian09 software, geometrical and electronic parameters such as the energy of HOMO and LUMO level, the Egap= EHomo- E Lumo and focused electronic parameters of the molecules were determined. It is obvious that the studied molecules show good photovoltaic properties. Thus, studied chemical structures are blended with acceptor compounds such as fullerene and PCBM derivatives in bulk-heterojunction solar cell. Quantic chemical calculations show that the studied compound present good electronic, optical and photovoltaic properties and can be used as potential electron donors in organic solar cells Heterojunction (BHJ).
