Abstract: We have fabricated a series of potassium-doped (K-doped) perovskite solar cells (PSCs). Structural investigations of the developed PSCs have shown that alkai doping affects the perovskite layer structure and morphology with the increase of the crystallite size and surface uniformity. K-doped samples exhibite higher photovoltaic (PV) performance and improved operational stability compared to the control series of undoped PSCs, due to retarded recombination processes.

Keywords: perovskite, solar cell, doping.
