In this article, we synthesize acidic magnesium-doped tin oxide quantum dots to modulate the bottom interface contact in wide-bandgap CsPbI 2 Br perovskite solar cells." Quantum dots are nanoscale ...

Figure 1. Schematic of a tunable microlaser based on phase-change perovskite gain medium, sandwiched between Au mirror and DBR reflector sitting on a quartz glass substrate, pumped by blue-violet ...

Our group was one of the first to discover that perovskite solar cells often have hysteretic current-voltage curves and was the first to realize that perovskites that contain both iodine and bromine ...

However, wide-bandgap perovskite formulations often suffer from phase segregation, where different components separate over time, which causes a decline in performance. One solution is to add rubidium ...

“Consequently, the resultant perovskite films exhibited a more homogenous perovskite phase with larger crystal grains and higher crystallinity.” They described the device in the paper ...

or a combination of these methods to prevent moisture spreading over the perovskite phase,” they said. In the manufacturing process, the scientists used dimethyl sulfoxide (DMSO), which is a ...
