Synthesis and Photovoltaic Properties of Diketopyrrolopyrrole Based Small Molecules for Solution Processed Organic Solar Cells |
초록 |
Two new small molecules, based on diketopyrrolopyrrole core flanked by cyanothiophene units (CN-DPP-CN, CN-TH-DPP-TH-CN) were synthesized by Suzuki coupling and explored as donors in solution processed organic solar cells (OSCs). The HOMO/LUMO energy levels of CN-DPP-CN, CN-TH-DPP-TH-CN having moderate band gap of 1.83 eV and 1.44 eV were estimated to be −5.63/−3.84 eV, −5.20/−3.75 eV respectively. The device efficiency was found to be 0.013, 0.21% for CN-DPP-CN, CN-TH-DPP-TH-CN respectively for BHJ solar cells. When CN-DPP-CN (0.05%) was added in P3HT:PC60BM device, its PCE was enhanced from 2.08% to 2.45% signifying its ability to be used as a potential n-type additive. |
