摘      要：SnO_(2)is widely used as the electron transport layer(ETL)in perovskite solar cells(PSCs)due to its excellent electron mobility,low processing temperature,and low *** the most common way of preparing the SnO_(2)ETL is spincoating using the corresponding colloid ***,the spin-coated SnO_(2)layer is sometimes not so compact and contains pinholes,weakening the hole blocking ***,a SnO_(2)thin film prepared through magnetron-sputtering was inserted between ITO and the spin-coated SnO_(2)acted as an *** strategy can combine the advantages of efficient electron extraction and hole blocking due to the high compactness of the sputtered film and the excellent electronic property of the spin-coated SnO_(2).Therefore,the recombination of photo-generated carriers at the interface is significantly *** a result,the semitransparent perovskite solar cells(with a bandgap of 1.73 eV)based on this double-layered SnO_(2)demonstrate a maximum efficiency of 17.7%(stabilized at 17.04%)with negligible ***,the shelf stability of the device is also significantly improved,maintaining 95%of the initial efficiency after 800-hours of aging.
