Chalcogenide Perovskite Thin Films by Ultrasonic Spray Pyrolysis Perovskite materials are currently a focal point of research in optoelectronics, including fields such as photodetection and solar energy utilization. Compared to the widely used halide perovskites, chalcogenide perovskites—distinguished by their excellent structural stability and unique optoelectronic properties—have emerged as promising new semiconductor materials. They hold the potential to overcome the performance limitations of traditional optoelectronic materials and are suitable [...]

Hot Pressing of Ultrasonic Sprayed MEA with Different Pt Loadings Pt loading-dependent effects of hot pressing on ultrasonic-sprayed membrane electrodes for PEM fuel cells Hydrogen energy, as a clean and low-carbon new energy carrier, is playing a vital role in the global energy transition. Proton exchange membrane fuel cells (PEMFCs) are one of the core devices for hydrogen energy utilization. They directly convert the chemical energy of hydrogen [...]

CuFe2O4/CuO Bilayer Protective Coating Deposited CuFe2O4/CuO bilayer protective coating deposited onto SUS430 interconnects by ultrasonic sprayed for solid oxide fuel cells In the field of clean energy, solid oxide fuel cells (SOFCs) are a power generation device with great development potential.
