  • Method for manufacturing a light-emitting electrochemical cell
    Patent number: 9515282
    Abstract: A method for manufacturing a light-emitting electrochemical cell (LEC) is disclosed. The LEC comprises a first electrode, a second electrode, and a first light-emitting active material in electrical contact with and separating the first and second electrodes. The first active material comprises mobile ions in an amount sufficient for doping the active material. The method comprises a step of depositing the first active material by spray-coating at an ambient gas pressure of at least about 1 kPa.
    Type: Grant
