제목 Impact of Outer Side-Chain Bulkiness of Selenophene-Incorporated Y-series Acceptors on the Properties of Eco-Friendly Organic Solar Cells
초록 Recently, in organic solar cell field, non-fullerene acceptors are being in the spotlight. Among them, Y-acceptor having A-D'AD'-A form recently achieved 18% efficiency. From this structure, various types of material modification have recently been made. However, the effect of the change in the outer chain has rarely been analyzed. In this study, three new materials were developed in which outermost selenophene in DA’D center backbone was introduced instead of thiophene in Y7. We investigated how the outer chain length affects the performance of eco-friendly processed organic solar cells. In addition to the different optimized performances, interestingly, it was confirmed that the rates of change of efficiency according to the thickness of the active layer were significantly different. Throughout this study, we intend to present design rules for non-fullerene acceptors that should be introduced for the future organic solar cells.
