Summary: A series of double donor organic dyes, ME101-ME106, designed in this work based on experimentally synthesized dye WD8, show higher stability and electron performance than the single donor dye. Among them, ME106 exhibits potential application value with a smaller energy gap and significant redshift compared to WD8. Results suggest that double donor dyes have stronger electron transfer capability, offering new insights for the design of high efficiency dye-sensitized devices.

Summary: Heteroaromatic units are commonly used as pi-spacers for sensitizers in dye-sensitized solar cells. The type of pi-spacer strongly influences the solar to electric power conversion efficiency of organic dyes, with electron-rich pi-spacers leading to higher efficiency. Molecular engineering plays a crucial role in developing high efficiency organic dyes for DSSCs.

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: Concerted companion (CC) dyes have been developed by linking the donors of porphyrin and organic dye units. The DSSCs based on the CC dyes XW85 and XW86 show higher J(SC) and PCE compared to the corresponding cosensitization systems. However, the PCEs for XW85 and XW86 are still lower than that of the acceptor-linked reference dye XW76. The study suggests that longer linking chains and avoidance of unfavorable alignments can improve the photovoltaic behavior of CC dyes.

Summary: In this study, oligothiophene molecules featuring two anchoring groups that do not possess strong donor moieties and are able to adopt V- and U-shape conformations were synthesized and used for DSSC fabrication. The smaller 5-thiophene dyes (5T2A, 5T2A-E) exhibited higher power conversion efficiencies (PCEs) compared to their larger 8-thiophene counterparts containing diacetylene units (8T4A, 8T4A-E).

Summary: By modulating the electronic properties of the sensitizer, the structure of the dye can be optimized for better device performance in dye-sensitized solar cells. A new unsymmetrical thiosquaraine sensitizer (SQ5S) has been designed and compared with its oxygen analog, SQ5. The incorporation of a sulfur atom in the acceptor unit of SQ5S dye resulted in a red-shifted absorption peak and panchromatic light harvesting response.

Summary: Three novel push-pull dyes, AJ502, TZ101 and TZ102, were synthesized and used as co-sensitizers in dye-sensitized solar cells (DSSCs). Among them, the co-sensitization of AJ502 with TZ101 and TZ102 significantly improves the power conversion efficiency of the DSSC, with the fluorine atoms in TZ101 playing a critical role in widening the active light capturing bands on the TiO2 film.
