Semi-transparent perovskite solar cells (ST-PSCs) are fabricated using a thin perovskite absorber layer. Moreover, the alkylamine hydrochlorides molecules with varied chain length are used to passivate the defects and facilitate charge transfer at the interface between perovskite and electron transport layer. Modified device exhibits a champion power...

The A-site defect regulates the bimetal exsolution. The exsolution process induces the activation of lattice oxygen and the generation of oxygen vacancies. The optimized surface structure and electron state show the change of adsorption energy for O2 and LiO2. The two growth mechanisms of the Li2O2 are modulated, demonstrating superior Li–O2 battery...

A Pr2Ni0.5Co0.5O4−δ (PNC) impregnation into La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) cathode enhances oxygen reduction reaction kinetics and proton transfer in protonic ceramic fuel cells (PCFCs). The PNC-LSCF cathode achieves a peak power density of 1857 mW cm− 2 at 700 °C with improved durability and lowered polarization resistance, offering a practical...

For the first time, the Co2.8, W3.8-NiFe LDH integrated catalyst with dual cocatalytic sites is developed, in which Co and W act as dual cocatalytic sites not only promote the *OH adsorption and protons desorption of Ni(Fe) sites for increasing critical *O coverage, but also regulate the electronic structure of Ni(Fe) sites to reduce the energy barrier...

A weakly solvating single-solvent electrolyte composed of tetrahydropyran stabilizes the lithium-metal anode and sulfurized polyacrylonitrile cathode effectively without the necessity of a fluorinated diluent. It enables stable cycling of Li-SPAN batteries at wide temperature ranges of 0–50 °C. Abstract Sulfurized polyacrylonitrile (SPAN)...

4-Aminomethyl cyclohexanecarboxylic acid (AMCA) addition with steric hindrance effect is reported to achieve the balance between sluggish mass transfer and rapid electrochemical reduction kinetics via the pull-push interplay for zinc ions. Abstract The electrode interface concentration polarization attributed to the contradiction between...
