Interfacial defect healing of In2S3/Sb2(S,Se)3 heterojunction solar cells with a novel wide-bandgap InOCl passivator

In2S3 has been regarded as a promising nontoxic alternative to CdS as an n-type electron transporting layer (ETL) for environmentally friendly antimony chalcogenide solar cells. However, the high-density of vacancy defects in In2S3 cause severe interfacial charge recombination in optoelectronic devi...
