Optimum silver contact sputtering parameters for efficient perovskite solar cell fabrication

The use of magnetron sputtering for deposition the metal electrode in perovskite solar cells has been limited because damage to organic hole transport layer by high kinetic energy particles during process. In this paper, a systematic investigation into effect power, argon flow rate, duration, and pressure on performance was conducted. results work show that power conversion efficiency 18.35% obtained solution-processed, air-fabricated with Ag contact prepared using sputtering. devices also exhibit an excellent short-current density 22.56 mA/cm2, open-circuit voltage 1.10 V fill factor 73.7%. reveals is most critical needs be carefully controlled minimise layer. This study demonstrates highly efficient can fabricated if parameters are optimised.
