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: In this study, three organic fluorine-containing dyes were designed and synthesized, and it was found that the introduction of fluorine can significantly broaden the absorption spectra of the dyes, but does not improve the light-harvesting capability of solar cells. One of the dyes, with fluorine substitution at the 3-position, showed a relatively high open-circuit photovoltage compared to the fluorine-free dye, and when co-sensitized with other dyes, it achieved a remarkably high power conversion efficiency and long-term stability. This work suggests that judicious molecular engineering and co-sensitization are promising strategies for highly efficient and stable solar cells.

Summary: Developing photosensitizers with high open-circuit voltage (V-oc) is important to improve the power conversion efficiency (PCE) of co-sensitized solar cells. By employing a carefully tailored organic sensitizer MS5 with copper electrolyte, the authors achieved a V-oc of 1.24V and recorded a PCE of 34.5% under ambient light.

Summary: A series of catechol-based sensitizers were presented for potential application in type II DSSCs. By analyzing the electronic and excited state properties of the dyes, it was found that introducing an ethylene spacer as a pi bridge enhances the charge transfer efficiency, regardless of electron-donating or electron-withdrawing substituents.

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: Here, a metal-free organic dye (CCPICPB) with panchromatic absorption in the near-infrared range was synthesized. The dye's photophysical properties were studied and validated through experimental and theoretical simulation. Pristine and calcium-doped TiO2 microspheres were synthesized using a solvothermal approach. The performance of CCPICPB dye on these materials was evaluated, with the Ca-TiO2 photoanode-based device showing higher efficiency. Co-sensitization of CCPICPB dye with Ru(II) dye resulted in further efficiency improvement, attributed to improved V-OC and J(SC) due to the dye's compensatory effect and inhibition of electron recombination.

Summary: Three N-phenylphenothiazine dyes were synthesized as photoactive materials for dye-sensitized solar cells. Dyes with furan and thiophene bridges exhibited longer ICT absorption wavelength and broader light absorption range. Dye with benzene bridge had inferior planarity but favored antiaggregation. DSSC based on dye with furan bridge achieved the highest photovoltaic conversion efficiency due to better JSC, VOC, and ff.

Summary: By synthesizing small molecule donors with different flexible side chains and blending them with acceptors to form SM-OSCs, it was found that adjusting the flexible side chains can significantly affect the photovoltaic performance of the devices. SM-OSC based on n-octyl chains demonstrated higher PCE value, possibly attributed to its better molecular stacking properties.
