A research team in India using a computational approach designed a perovskite solar cell combining a Dion-Jacobson (DJ) 2D layer with a 3D lead-free halide perovskite, a combination that could ...

“We design a photo-ferroelectric 2D/3D/2D perovskite junction by integrating a 2D ferroelectric perovskite single crystals in the perovskite bulk, as a tool to manipulate the perovskite ...

However, tin-based 3D perovskites are much less stable than their lead-bearing cousins, and they can degrade within hours when exposed to the atmosphere. “But our tin-based 2D perovskite can ...

Rather, the 2D arrangement is simply more rugged than the 3D perovskite, which provides protection and stability to the working parts of the cell. The research team was quick to point out in their ...

"We could eventually see THPs used for engineering challenges, including as a lightweight solution to power electric aircraft—the sky really is the limit." More information: Dongxu He et al, ...
