dc.description.abstractRecently, enormous efforts have been made to develop the efficient, lead (Pb) free and stable perovskite solar cells (PSCs). In this regards, various strategies were applied and the optoelectronic properties of various Pb free perovskites such as (CH3NH3)3Sb2I9, (CH3NH3)3Bi2I9, Cs3Sb2I9, Cs3Bi2I9, CH3NH3SnI3 and CH3NH3GeI3 etc have been investigated. However, the photovoltaic performance of the developed PSCs was still low and presence of organic moieties in common hole-transport materials (HTMs) shows poor stability against moisture and heat. Herein, we have investigated the optoelectronic properties of all inorganic Pb free perovskites (Cs3Sb2I9=1 and Cs3Bi2I9=2) and employed novel strategies (dissolution-recrystallization) to prepare the efficient Pb free PSCs. The band gaps of the 1 and 2 were found to be 2.2 eV and 2.0 eV, respectively. The developed PSCs with 1 and 2 exhibited the power conversion efficiency of 0.68% and 1.087%, respectively. © 2020 Wiley-VCH GmbHen_US
