Perovskite solar cells (PSCs) based on planar SnO2 (p㏒nO2) demonstrate excellent performance due to the superior properties of SnO2 as electron transporting layer (ETL). However, at present mesoporous SnO2 (m㏒nO2) still lags behind p㏒nO2 due to problems in the fabrication process of m...
Metal halide perovskite solar cells (PSCs) have garnered much attention due to their impressive development in power conversion efficiencies (PCEs). Benefiting from high electron mobility and good energy-level alignment with perovskite, aqueous SnO2 as an electron transport layer has been widely...
SnO2–SiO2 DBRs with various SiO2 thicknesses were synthesized by a simple spin-coating process. By combining DBRs and TiO2-free perovskite devices, blue-, purple-, and yellow-colored perovskite solar cells were successfully fabricated and showed PCEs of 9.52%, 5.99% and 6.85%, respectively....
For low temperature (≤180 °C) processed perovskite solar cells (PSCs), SnO2 has been proven to be one of the most effective electron transporting layer. However, problems, such as poor electric conductivity and high defect density, inevitably exist in the SnO2 films which...
perovskite solar cellsSnO2then retarded charge recombination and thus increased both of the VOC and fill factor (FF).[34] The high quality of SnO2/ perovskite heterojunction implies improved electric parameters such as RS, RSH extracting from the internal resistance of the device based on the J-...
