It bonds with its silicon neighbor atoms, but one electron is not involved in bonding. Instead, it is free to move inside the silicon structure. A solar cell consists of a layer of p-type silicon ...

An international team has combined organic synthesis with predictive models to discover new functional materials that enhance performance of hole transport layers used in perovskite solar cells.

The process to prevent the deformation of the photoactive layers is described in the paper Impact of strain relaxation on performance of α-formamidinium lead iodide perovskite solar cells ...

One proposed strategy to boost the stability, PCEs and reliability of perovskite solar cells entails the passivation of 3D perovskite light-harvesting layers with 2D perovskites. These 2D layers ...

So researchers have tried to get around this by putting different layers of material together in a what's termed a tandem cell approach. "Tandem cell means you have two devices built together in ...
