Perovskite solar cells (PSCs) have reached certified efficiencies of up to 23.7% but suffered from frailness and instability when exposed ambient atmosphere. Zinc oxide (ZnO), used as electron transport layer (ETL) on PSCs, gives rise excellent electronic, optic, photonic properties, yet the Lewis basic nature ZnO surface leads deprotonation perovskite layer, resulting in serious degradation PSCs using ETL. Here, we report a simple effective strategy convert into ZnS at ZnO/perovskite...
Abstract An organic–inorganic hybrid electrolyte based on a cyclic Ti‐oxo cluster as the inorganic core and naphthalene‐based organic ammonium bromide salts was developed with easy synthesis low cost. The new exhibits excellent solubility in methanol, aligned work function, good conductivity, amorphous state thin film, enabling its successful application cathode interlayer solar cells high power conversion efficiency of 17.19 %. This demonstrates that electrolytes are kind semiconductor,...
Perovskite films prepared with CH3NH2 molecules under ambient conditions have led to rapid fabrication of perovskite solar cells (PSCs), but there remains a lack mechanistic studies and inconsistencies operability in their production. Here the crystal structure CH3NH2-CH3NH3PbI3 was analyzed involve hydrogen bonds (CH3NH2···CH3NH3+) has guided facile, reproducible preparation high-quality conditions. Hydrogen within CH3NH2···CH3NH3+ dimers were found intermediates, accompanied by 1D-PbI3-...
Lithium (Li) metal is a favorable anode for most energy storage equipment, thanks to its higher theoretical specific capacity. However, nonuniform Li nucleation/growth results in large-sized and irregular dendrites generated from the anode, which causes rapid capacity fade serious safety hazard, hindering widespread practical applications. In this paper, with aid of lithium nitrate (LiNO3) additive carbonate-based electrolyte, shows low hysteresis excess 1000 h at current density 0.5 mA...
