Perovskite Solid-State Electrolytes for Lithium Metal Batteries
Solid-state lithium metal batteries (LMBs) have become increasingly important in recent years due to their potential to offer higher energy density and enhanced safety compared to conventional liquid electrolyte-based lithium-ion batteries (LIBs). However, they require highly functional solid-state electrolytes (SSEs) and, therefore, many inorganic materials …
Advanced Perovskite Solar Cells
The prepared films used in perovskite batteries also have some problems, such as low viscosity of precursor solution, low crystallinity caused by fast crystallization, and poor contact between substrate and perovskite layer. ... It has high conductivity, which can reduce the series resistance and improve the Fill factor (FF); (3) …

Effect of absorber layer, hole transport layer thicknesses, and its ...
A thick HTL can cover an uneven perovskite surface uniformly, however it leads to an increase in series resistance and lower hole mobility in HTL as compared to perovskite layer. Additionally, since MAPbI 3 perovskite contains crystallites, if a very thin HTL is used, perovskite crystals can protrude through HTL and contact the bottom …
