Abstract：

Antimony　selenosulfide　(Sb2(S,Se)3)　solar　cells　have　achieved　an　efficiency　of　over　10.0%.　However,　the　uncontrollable　hydrothermal　process　makes　preparing　high-quality　Sb2(S,Se)3　thin　films　a　bottleneck　for　efficient　Sb2(S,Se)3　solar　cell.　To　address　this　problem,　triethanolamine　(TEA)　additive　is　innovatively　utilized　to　regulate　the　reaction　kinetic　process　of　Sb2(S,Se)3　thin　films　in　this　work.　The　results　show　that　TEA　chelator　can　realize　the　time-domain　control　of　the　reaction　process,　optimizing　the　Se/(S+Se)　elemental　distribution　of　Sb2(S,Se)3　thin　film　and　shrinking　the　bandgap　offset　of　Sb2(S,Se)3　thin　film.　Meanwhile,　the　(021)　and　(061)　crystal　orientation　of　Sb2(S,Se)3　thin　film　are　enhanced　and　the　harmful　VSe1　defects　in　Sb2(S,Se)3　solar　cells　are　passivated.　Interestingly,　a　uniform　back　surface　gradient　for　Sb2(S,Se)3　thin　film　is　formed　to　reduce　the　minority　carrier　recombination　at　the　back　contact,　increase　the　photocurrent　and　decrease　the　diode　current　of　Sb2(S,Se)3　solar　cells.　Finally,　the　Jsc　and　FF　of　Sb2(S,Se)3　solar　cells　are　significantly　improved　by　8.6%　and　5.5%　respectively,　and　the　open-circuit　voltage　deficit　of　the　device　is　reduced　by　44 mV,　which　leads　to　an　efficiency　of　9.94%　which　is　the　highest　values　of　Sb2(S,Se)3　solar　cells　by　sodium　selenosulfate　system.　©　2024　Wiley-VCH　GmbH.
