BaTiO3/polyvinylidene fluoride (BT/PVDF) is the extensive reported composite material for application in modern electric devices. However, there still exists some obstacles prohibiting further improvement of dielectric performance, such as poor interfacial compatibility and low constant. Therefore, depth study size dependent polarization surface modification BT particle technological importance developing high performance BT/PVDF composites. Here, a facile molten-salt synthetic method has...
Abstract Flexible and stretchable conducting composites that can sense stress or strain are needed for several emerging fields including human motion detection personalized health monitoring. Silver nanowires (AgNWs) have already been used as conductive networks. However, once a traditional polymer is broken, the network subsequently destroyed. Integrating high pressure sensitivity repeatable self‐healing capability into flexible sensors represents new advances performance sensing. Herein,...
Abstract Photovoltaic (PV) technology is ready to become one of the main energy sources of, and contributers to, carbon neutrality by mid‐21st century. In 2020, a total 135 GW PV modules were produced. Crystalline silicon solar cells dominate world's market due high power conversion efficiency, stability, low cost. Silicon heterojunction (SHJ) are promising technologies for next‐generation crystalline cells. Compared commercialized homojunction cells, SHJ have higher lower temperature...
Inverted p-i-n structure perovskite solar cells (PSCs) have attracted considerable attention in consideration of high-efficiency, long-term stability, and cost reduction, which represent the key challenges advancing commercialization PSCs. In order to address issue defect-related nonradiative recombination, we enhanced interfacial passivation between layer electron transfer with crown ether derivatives By a combination first-principles calculations, photoluminescence (PL) time-resolved...
Abstract Nickel oxide (NiO X ) has a crucial role in enhancing the efficiency and stability of p‐i‐n inverted perovskite solar cells (PSCs), which hold great potential for commercialization. However, improving contact passivation between perovskites NiO is challenge due to hindered buried interface. In order address this issue, self‐assembled monolayers (SAMs) are introduced as buffer layer prevent direct non‐radiative recombination. While, large dipole moment SAMs increases work function ,...
