They conclude that thermal stress is the decisive factor in the degradation of metal-halide perovskites. Based on this, they derive the most promising strategies to increase the long-term ...

While defect ordering has been observed numerous times in perovskite oxides, the same cannot be said about hybrid halide perovskites, composed of an organic cation, a metal cation, and a halide anion.

A group of researchers led by the Chung-Ang University in South Korea has designed a tin halide perovskite (Sn-HP) solar cell that utilizes an additive known as 4-Phenylthiosemicarbazide (4PTSC ...
