Perovskite solar cells are a low-cost alternative to conventional silicon-based cells, but so far have only been produced on a small scale as they are difficult to manufacture. A team of researchers from the US and China has now developed a scalable method to create perovskite solar cells by spraying on the electron transport layer (ETL). … "Very little research has been done on ETL [electron transport layer] options for the planar p-i-n design," said André Taylor, an associate professor in the NYU Tandon School of Engineering's chemical and biomolecular engineering department. "The key challenge in planar cells is, how do you actually assemble them in a way that doesn't destroy the adjacent layers?"
