Field-effect passivation and chemical passivation were evaluated by fixed oxide charge (Q f) and interface defect density (D it),respectively,using capacitance-voltage measurement.The results show that O 2 annealing gives a high Q f of - 3.9 × 10 12 cm -2 ,whereas FG annealing leads to excellent Si interface hydrogenation with a low D it of 3.7 × 10 11 eV -1 cm -2 .Finishing Chemicals Böhler WeldingChemical cleaning can be expected to produce superior results.This is because most mechanical methods tend to produce a rougher surface while chemical methods reduce the risk of surface contamination.However,chemical cleaning may be limited not only by local regulations on environmental and industrial safety,but also by waste disposal problems.Imperfections and their passivation in halide perovskite Imperfections and their passivation in halide perovskite solar cells Chem Soc Rev .2019 Jul Changsha,Hunan 410083,China.PMID 31187791 DOI 10.1039 /c8cs00853a or chemical conversion have proven effective in mitigating the negative impacts of these deep traps.Shallow level charge traps themselves may contribute little to non
