Theoretical design and study on hexamolybdate-based organic-inorganic hybrids with double D-π-A chains for high performance p-type dye-sensitized solar cells (DSSCs)
The introduction of POM leads to red shift and broadened absorption peak. The energy gaps for systems 4–6 are smaller than those of systems 1–3. Thiophene as π linker in system 5 has the best performance.
