Another way of producing perovskite cells
South Koreans have developed two solar cells made of perovskite: a polymer
made with peppermint oil and another using nut-flavoured food additives. The new dopant-free hole-transporting polymer allows for longer durability of the devices and prevents lead leakage. The cells achieved efficiencies of 19.9% and 21.2%, respectively. The use of these two organic solvents replaces the toxic chemicals used in previous manufacturing processes.
