However, oxide perovskites are not the type of material currently used in photovoltaic (PV) solar cells. Instead, perovskite solar cells primarily use organic-inorganic halides with the most common being methylammonium lead iodide (MAPbI3). However, just because it is the most common does not mean it is the only viable composition.
