Lead-based　perovskite　solar　cells　had　reached　a　bottleneck　and　demonstrated　significant　power　conversion　efficiency　(PCE)　growth　matching　the　performance　of　traditional　polycrystalline　silicon　solar　cells.　Lead-containing　perovskite　solar　cell　technology　is　on　the　verge　of　commercialization　and　has　huge　potential　to　replace　silicon　solar　cells,　but　despite　the　very　promising　future　of　these　perovskite　solar　cells,　the　presence　of　water-soluble　toxic　lead　content　is　a　growing　concern　in　the　scientific　community　and　a　major　bottleneck　for　their　commercialization.　The　less　toxic,　tin-based　perovskite　solar　cells　are　promising　alternatives　for　lead-free　perovskite　solar　cells.　Like　lead-based　perovskite,　the　general　chemical　formula　composition　of　tin-based　perovskite　is　ASnX(3),　where　A　is　a　cation　and　X　is　an　anion　(halogen).　It　is　evident　that　tin-based　perovskites,　being　less-toxic　with　excellent　photoelectric　properties,　show　respectable　performance.　Recently,　numerous　studies　reported　on　the　fabrication　of　Sn-based　perovskite　solar　cells.　However,　the　stability　of　this　novel　lead-free　alternative　material　remains　a　big　concern.　One　of　the　many　ways　to　stabilize　these　solar　cells　includes　addition　of　dopants.　In　this　context,　this　article　summarizes　the　most　important　fabrication　routes　employing　dopants　that　have　shown　excellent　stability　for　tin-based　perovskite　photovoltaics　and　elaborates　the　prospects　of　lead-free,　tin　based　stable　perovskite　photovoltaics.
