CH3NH3PbI3 perovskite materials deposited on ZnO electron transport layers (ETLs) undergo decomposition during annealing in N2 atmosphere. We found that this decomposition can be retarded by restricting sublimation. Moreover, the decomposition upon t

Group VB metals, as candidates for hydrogen separation metallic membrane, suffer from low surface catalytic activity and mechanical integrity issues due to hydrogen embrittlement, which limited their practical application for mixed gas purification.

For pure hydrogen separation, palladium was deposited on surface-treated polybenzimidazole (PBI-HFA, 4,4′-(hexafluroisopropylidene)bis(benzoic acid)) via the vacuum electroless plating technique (VELP). Since the hydrophobic characteristics of the

Generally, Pd membranes used for H2 purification are deposited on porous stainless steel (SS) or porous ceramics. These membranes are thick ( > 5 μm) because of the large pore size of the support used; hence, such thick membranes are not cost-effect

Inorganic-organic mesoscopic solar cells become a promising alternative for conventional solar cells. We describe a CH3NH3PbI3 perovskite-sensitized solid-state solar cells with the use of different polymer hole transport materials such as 2,2′,7,7
