Effect of Interfacial Engineering in Solid-State Nanostructured Sb sub(2)S sub(3) Heterojunction Solar Cells

Surface treatment by decyl-phosphonic acid (DPA) reduces the recombination and increases the open circuit voltage and the fill factor of the inorganic-organic Sb sub(2)S sub(3) hetrojunction solar cell. It is revealed that the DPA attaches to both surfaces, the uncovered TiO sub(2) surface and the S...

Zusammenfassung:Surface treatment by decyl-phosphonic acid (DPA) reduces the recombination and increases the open circuit voltage and the fill factor of the inorganic-organic Sb sub(2)S sub(3) hetrojunction solar cell. It is revealed that the DPA attaches to both surfaces, the uncovered TiO sub(2) surface and the Sb sub(2)S sub(3) surface. This cell produces a power conversion efficiency of 3.9% under 1 sun intensity.
