A Non-Fullerene Small Molecule as Efficient Electron Acceptor in Organic Bulk Heterojunction Solar Cells
摘要:
A novel n-type small molecule FFI-1 was synthesized as the electron acceptor to replace PCBM in solution-processed organic BHJ solar cells. Its LUMO level (around -3.5 eV) both matches the work function of the cathode and increases VOC of the devices, making it a promising acceptor candidate. With P3HT: FFI-1 (1: 2 w/w) as active layer and LiF/Al as the cathode, the best power conversion effi ciency (PCE) reaches 1.86%.

Acenaphthenequinone was obtained in 95% yield when the reaction of 1-acenaphthenone with N-bromosuccinimide was carried out in dimethyl sulfoxide at room temperature. Under similar conditions, several acenaphthenequinones were prepared from the corresponding 1-acenaphthenones in good yields.

Visibly transparent photovoltaic devices are disclosed, such as those are transparent to visible light but absorb near-infrared light and/or ultraviolet light. The photovoltaic devices make use of transparent electrodes and near-infrared or ultraviolet absorbing visibly transparent photoactive compounds, optical materials, and/or buffer materials.
A series of fluoranthene-fused imide derivatives were facilely developed through a Diels−Alder reaction followed by decarbonylation. The investigation of their photophysical and electrochemical properties demonstrated that their LUMO levels were effectively tuned from −3.2 to −3.8 eV through the introduction of a fused imide unit, which provides a platform to design new air-stable and solution-processable
