Improving perovskite solar cell performance with phenethyl ammonium chloride

An international research team developed a perovskite solar cell performance-boosting treatment based on phenethyl ammonium chloride (PEACl) that is also claimed to reduce the number of process steps. With this technique, the group built a champion device with a 20. 9% efficiency. An international research team developed a method to fabricate perovskite thin films using a precursor known as phenethyl ammonium chloride (PEACl) in a simultaneous deposition and passivation step. "Such a simplified process can enable researchers to make cells with more consistent quality," Tim Kodalle, the scientist ...
