Abstract
The present disclosure relates to an electron transport layer for a perovskite solar cell, which is tin oxide (SnO, 0<x<1) comprising oxygen vacancies, wherein the oxygen vacancies are passivated by oxidized black phosphorus quantum dots (O-BPs), and a perovskite solar cell including the same. The electron transport layer for a perovskite solar cell of the present disclosure can prevent phase transition to a structure having semiconductor properties not suitable for solar cells, such as δ-FAPbIor PbI, due to the occurrence of iodine interstitials (I) in the perovskite structure caused by deficiency of oxygen atoms in SnOat the interface, by passivating the oxygen vacancies with oxidized black phosphorus quantum dots (O-BPs) containing multiple P═O bonds.
