Micro-light-emitting diodes (μLEDs) have garnered significant interest as light sources for gas sensors due to their advantages, such as room temperature operation and low power consumption. However, ...

The research team developed the perovskite solar cell with a spin-coated bilayer tin oxide electron transport layer that boosts charge extraction, achieving a 4.52% efficiency and improved stability.

SnO 2 has been widely used as electron transport layers (ETLs) for efficient perovskite solar cells (PSCs) due to its high transparency, high electron mobility, and favorable band alignment. PSCs ...
