| 제목 | New Design and Synthesis of Near-Infrared Non-Fullerene Acceptor with Low Synthetic Complexity for High Performance and Semitransparent Organic Solar Cells |
| 초록 | Semitransparent organic solar cells (STOSCs) have many advantages, such as flexibility, lightweight, high transparency, and natural color in potential applications for building integrated photovoltaics, vehicles, and portable electronic mobiles. By introducing non-fullerene acceptors (NFAs) with enhanced near-infrared (NIR) absorption region of solar spectrum, it can be reached STOSC with both high efficiency and visible transmittance. However, it is a quite hard to develop materials satisfying both properties with low cost. In this study, we report the new NIR NFAs with low synthetic complexity and high performance. This design is so reasonable in aspects to raw material costs, synthetic steps, and overall yields. Mostly combinations with inden-malonitrile derivatives as the end group showed a ultra-low band gap below 1.35 eV. In addition, their average visible transmittances reached over 60% in region of 380-780 nm. Our work demonstrated the great potential in application to STOSCs. |
