Summary: The study explored a series of amphiphilic indoline-based unsymmetrical squaraine dyes, where alkyl groups and glycolic chain were systematically modified to control self-assembly and improve interfacial properties. In nonaqueous DSSCs, increasing the number of carbon atoms in alkyl groups enhanced photovoltaic efficiencies. Addition of chenodeoxycholic acid improved efficiency, while increased carbon atoms in the alkyl groups had a detrimental effect on aqueous DSSC efficiency.

Summary: The study found that adding 6 wt% graphene oxide (GO) into iodide-triiodide (I-/I-3(-)) electrolyte can significantly improve the performance of dye sensitized solar cells (DSSCs), but performance is suppressed when the GO content exceeds 6 wt%. This is because an appropriate amount of GO can enhance hole transport, while an excessive amount of GO will reduce diffusivity.

Summary: In this study, a biocompatible and biodegradable zwitterionic surfactant SB3-14 was used to solubilize the poorly water-soluble monomer EDOT, and its advantage over the nonionic surfactant C12E10 in the anodic polymerization of EDOT was demonstrated. Compared with C12E10, SB3-14 showed no adsorption on the electrode and no oxidation at high oxidative polymerization potential for EDOT. These unique properties enhanced the electropolymerization rate and current efficiency.

Summary: Thin films of solid-state polymer electrolytes (SSPEs) have been developed for dye-sensitized solar cells (DSCs) for the first time. Gel-electrolytes are prepared by utilizing a blend of poly(ethylene oxide) (PEO)/polyethylene glycol (PEG) and an acetonitrile-based iodide liquid electrolyte, and then cast onto a glass substrate to fabricate solvent-free SSPEs by evaporating the solvent. The SSPE films are sandwiched between photoelectrodes and counter electrodes to assemble the solid-state DSCs, and the PCE can be improved by introducing TiO2 nanofillers in the SSPEs. The high stability of the solid-state DSCs is demonstrated with a retention of 98% of their original efficiency after a 700-hour test period.

Summary: This study investigates the effect of the network structure of hydrogels on the performance of quasi-solid gel electrolytes in DSSCs. Increasing cross-linking during synthesis improves conductivity but does not necessarily increase energy conversion efficiency in DSSCs. Cross-linking also affects the swelling, wetting, and morphological properties of the hydrogels.

Summary: This study investigates the technical feasibility of using graphene produced by chemical vapor deposition (CVD) to replace tin oxides in dye-sensitized solar cells (DSSCs). Graphene shows higher transparency and electrical conductivity compared to tin oxides, resulting in larger open circuit voltage and short circuit current density. However, the higher sheet resistance of graphene leads to a lower fill factor. Despite being much thinner than tin oxides, graphene-DSSCs and tin oxide DSSCs exhibit similar power conversion efficiencies.

Summary: This study demonstrates the profound impact of doping status of organic hole transport materials (HTMs) on the light soaking effect (LSE) in perovskite solar cells. Undoped HTMs show a tenfold efficiency enhancement under LSE, attributed to increased film conductivity and changes at the interface. Chemical and structural analysis also reveal that halide ions migration and subsequent photodoping of organic HTMs significantly improve film conductivity and hole mobility, leading to enhanced photostability of the devices.

Summary: Chemical doping of organic semiconductors can greatly improve their optoelectronic performance, but the correlation between doping counter ions and charge-transport mechanism is not well understood. This study reveals that the anion-dependent degree of delocalization of lithium-based dopants plays a significant role in determining the doping kinetics and conductivity of organic hole transport layer. By modulating the anion dissociation, the efficiency and stability of organic electronics can be simultaneously improved.

Summary: In this study, interlayer molecules with different side groups were designed to investigate the correlation between defect-passivation strength and interfacial carrier dynamics in polycrystalline perovskite. It was found that the introduction of Cl-grafted molecules or cyanide (CN) as a side group led to destructive effects and deformation of the perovskite structure. However, the incorporation of carbonyl (C=O) as the side group (TPA-O) effectively promoted carrier-collection yield and defect passivation, resulting in high efficiency and stability in perovskite solar cells. This work provides a potential strategy for improving the performance of perovskite solar cells.
