Summary: New anthracene-bridged organic dyes CXC12 and CXC22 are designed and synthesized for high-efficiency dye-sensitized solar cells (DSSCs) under dim light. The addition of anthracene-acetylene group in CXC dyes extends the pi-conjugation of the molecules, resulting in improved absorption and molar extinction coefficient. Among the three anthracene-based dyes, CXC22 shows the most appropriate molecular structure for light harvesting and balancing dye loading and molecular aggregation, achieving a remarkable power conversion efficiency of 37.07% under dim-light conditions.

Summary: The design and synthesis of two novel D-A dyes cTPAPh-NO2 and cTPABT-PyCN2 were reported, and their photophysical and electrochemical properties were investigated. The attachment of carboxyl groups reduced the light harvesting and intramolecular charge separation ability of cTPAPh-NO2. In contrast, cTPABT-PyCN2 exhibited weak fluorescence and efficient intramolecular charge separation characteristics. These dyes showed promising potential as p-type sensitizers with effective charge separation characteristics in dye-sensitized solar cells.

Summary: Metal ferrite oxides (MFe2O4) and iron oxide (Fe2O3) were investigated as unassisted operation for solar light harvesting photoelectrochemical cell (PEC). Different metal ferrite oxides, such as CuFe2O4, NiFe2O4, and ZnFe2O4, were synthesized using electrochemical deposition method. The crystal structure, surface morphology, and chemical composition of Fe2O3 and metal ferrite oxides were characterized using various techniques. CuFe2O4 showed p-type semiconductor characteristic, while Fe2O3, NiFe2O4, and ZnFe2O4 exhibited n-type semiconductor characteristic. Therefore, the coupling between n-type and p-type semiconductors can form PEC without external bias. CuFe2O4 was set as the photocathode, and the others were set as the photoanode. Both parallel and tandem configurations were explored. All materials can be used as unbiased PEC, and the best performance was observed with Fe2O3 coupled with CuFe2O4. The maximum photocurrent of Fe2O3-CuFe2O4 tandem PEC was around 6 mu A/cm(2) under parallel illumination conditions.

Summary: Detailed pictures of excited-state proton transfer reactions in 8-hydroxyquinoline and its water clusters were systematically investigated using DFT and TD-DFT methods. The study revealed that intraHB and interHB interactions between 8HQ and water clusters become stronger in the first excited state, and ESIntraPT and ESInterPT reactions can occur in femtoseconds. The simulations also showed that the number of water molecules affects the tautomer species and initiates multiple proton transfer reactions. These results provide insights into the phototautomerization process and photodynamics that cannot be observed experimentally.
