Greener chemistry brings low-toxicity perovskite solar cells closer to production

Researchers at the University of Surrey have developed a greener chemistry for perovskite solar cells that can be coated onto thin, flexible surfaces at room temperature, similar to newspaper printing, without the toxic solvents the process previously relied on.

• Perovskite panels can be coated onto thin flexible surfaces
• The process runs at room temperature like newspaper printing
• The new method avoids toxic solvents
• The work brings perovskite cells closer to mass production
