Sodium acetate was introduced to help break down the solar cell’s individual materials. Sodium iodide, by contrast, was added to help reform the separated perovskite crystals so that they could ...

When it is exposed to air, the iron begins to rust. This rusting process produces heat. The second contains a solution of the chemical sodium acetate and a small metal disc. When the disc is bent, ...
