Scientist advance slot-die coated perovskite solar cells and also ink properties
Researchers from Germany's Helmholtz-Zentrum Berlin (HZB) and also HTW Berlin have taken a look at exactly how precursor inks influence the quality of perovskite thin films. The best cells were scaled approximately minimodule dimension. The team revealed that when slot-die covering the halide perovskite layers on large locations, ribbing results may occur yet can be protected against by adjusting the precursor ink's rheological properties.

Stability of perovskite solar cells reaches next milestone
Perovskite semiconductors promise highly efficient and affordable solar cells. Nonetheless, the semi-organic product is very sensitive to temperature differences, which can swiftly cause fatigue damages in typical outdoor usage. Adding a dipolar polymer compound to the precursor perovskite solution assists to neutralize this.

Perovskite solar cells: Interfacial loss systems revealed
Losses take place in all solar cells. One cause is the recombination of cost carriers at the interfaces. Intermediate layers at such interfaces can reduce these losses via so-called passivation. Self-assembled monolayers (SAMs) with a carbazole core are particularly well suited for the passivation of semiconductor surfaces constructed from perovskite products.
