Acetamidinium-substituted methylammonium lead iodide based perovskite solar cell on flexible stainless-steel substrate

Acetamidinium-substituted methylammonium lead iodide (MAPI) based perovskite solar cells (PSCs) have shown promising performance. This work demonstrates acetamidinium-substituted MAPI-based PSCs fabricated on stainless-steel substrate which can be used for various flexible applications. The preliminary fabrication runs exhibited the power conversion efficiency (PCE) upto 5.3%. The short circuit current density (J(sc)), open circuit voltage (V-oc) and fill factor (FF) obtained for the best PCE device are -12.69 mA/cm(2), 0.77 V and 54% respectively. The work is currently in progress to obtain better performing solar cell devices and understand the responsible physical mechanisms behind their behavior.
