EMPLOYING LEAD THIOCYANATE ADDITIVE TO REDUCE THE HYSTERESIS AND BOOST THE FILL FACTOR OF PLANAR PEROVSKITE SOLAR CELLS.

Lead thiocyanate in the perovskite precursor can increase the grain size of a perovskite thin film and reduce the conductivity of the grain boundaries, leading to perovskite solar cells with reduced hysteresis and enhanced fill factor. A planar perovskite solar cell with grain boundary and interface passivation achieves a steady-state efficiency of 18.42%.
