The thermal stability of high‐efficiency organic photovoltaics (OPVs) is critical to the manufacturing of this technology. Therefore, targeted strategies and approaches shall be developed to improve efficiency and stability, simultaneously. Herein, a seleno twisted benzodiperylenediimides (TBD‐PDI‐Se) acceptor‐doping strategy is taken advantage of to demonstrate the ternary bulk heterojunction OPVs...
Long microchannels with thin walls, small width, and nanoholes or irregular shaped microgaps, which are similar to capillaries or cancerous vessels, are urgently needed to simulate the physiological activities in human body. However, the fabrication of such channels remains challenging. Here, microchannels with designable holes are manufactured by combining laser printing with line‐contact capillary‐force...
Developing appropriate sulfur cathode materials in carbonate‐based electrolyte is an important research subject for lithium‐sulfur batteries. Although several microporous carbon materials as host for sulfur reveal the effect, methods for producing microporous carbon are neither easy nor well controllable. Moreover, due to the complexity and limitation of microporous carbon in their fabrication process,...
Much effort has been made to search for high energy and high power density electrode materials for lithium ion batteries. Here, a composite structure among Ge, C and Cu3Ge in Cu3Ge/Ge/C materials with a high rate performance of lithium batteries has been reported. Such Cu3Ge/Ge/C composite is synthesized through the in‐situ formation of Ge, C and Cu3Ge by one‐pot reaction. Density function theory...
