“…The ion supporting PANI provides channels for ion transport, which promotes charge transport of the iodide anions in the gel electrolyte. This would facilitate the decreased resistance R d for the DSSCs based on PANI/PEO and GOS‐PANI/PEO gel electrolytes . Nevertheless, higher R d values were observed for the DSSCs (DSSC III‐10 and DSSC IV‐10) incorporated with 10 wt % of G2P or G4P in PEO gel electrolyte.…”

“…The PANI plays the role of both hole and ionic charge transporting moieties. Moreover, the ion supporting PANI provides channels for ion transport, which is favorable for the enhancement of D app of triiodide ions, and ionic conductivity of polymer gel electrolytes . Moreover, the PANI sample also provides pathways for hole‐transport back to the contact electrode, resulting in good charge balance in electrolytes .…”

In this study, photovoltaic (PV) properties of dyesensitized solar cells (DSSCs) incorporated with graphene oxide nanosheet-polyaniline (GOS-PANI) nanohybrid/poly(ethylene oxide) (PEO) blend gel electrolytes were investigated. Chemical structure and composition of GOS-PANI nanohybrids were characterized by Raman spectroscopy and X-ray photoelectron spectroscopy. The images of transmission electron microscopy revealed that PANI nanorods were anchored to the single-layered GOS for the GOS-PANI nanohybrids. Ionic conductivities of the GOS-PANI/PEO-based gel electrolytes were measured using a conductivity meter. The electrochemical catalytic activities of the GOS-PANI nanohybrids were determined through cyclic voltammetry. These GOS-PANI nanohybrids were served as the extended electron transfer materials and catalyst for the electrochemical reduction of I 3 2 . Due to the enhancement of the ionic conductivity and electrochemical cat-alytic activity of the gel electrolyte, better PV performance was observed for the DSSCs based on the GOS-PANI containing electrolytes as compared to the pristine PEO electrolyte-based DSSC sample. Moreover, PV performances of the GOS-PANI/ PEO-based DSSCs were closely related to the PANI content of GOS-PANI nanohybrids. The highest photo-energy conversion efficiency (5.63%) was obtained for an optimized GOS-PANI/PEO (5:95, w/w) blend gel electrolyte-based DSSC sample.

“…In connection with the development of aforementioned HTMs, several reports have been already explored with many organic molecules that exhibit low molecular weight and generally consist of phenothiazine, phenoxazine, carbazole triphenylamine, conjugated polymers, and imidazole for application in both DSCs and PSCs. [ 8,9,22–29 ] However, these HTMs were reported with low efficiency and best resulted when applied with lithium salts such as LiTFSI, 4‐TBP, and N(PhBr) 3 SbCl 6 , [ 28 ] which kindly direct for better pore‐filling property. Thus, it is necessary to design SOHTMs with the aforementioned unique property.…”

With the exploration of new building blocks, a series of small organic hole transporting materials (SOHTMs) are designed and synthesized through simple microwave irradiation and systematically investigated in solid‐state dye‐sensitized solar cells (ss‐DSCs) and perovskite solar cells (PSCs). These V‐shaped SOHTMs having A–D–A architecture are endowed with low cost, better thermal stability, and good optical and electrochemical property, which respond to low indoor light and 1 sun illumination. The SOHTMs contain dibenzothiophene (DBT) and dibenzofuran (DBF) as core donors substituted with heteroaromatic molecules like naphthalene and indole, which are coded as SPH 1–SPH 4. ss‐DSCs and PSCs with SPH 4 (with LiTFSI) as SOHTMs exhibited a power conversion efficiency (PCE) amounting to 5.2% and 15.4%, respectively, under 1 sun illumination. Moreover, the applications of ss‐DSCs and PSCs in indoor environments are studied. Due to the good match with the indoor light emitting diode (LED) source, SPH 4 delivered PCEs of 26.3% (for ss‐DSCs) and 23.9 % (for PSCs) under 1800 lux illumination, which are very close to the PCE values obtained for standard hole transporting materials (HTMs) like spiro‐OMeTAD. Thus, these new SOHTMs provide the ultimate solution for the fabrication of photovoltaic devices, resulting in superior PCE under indoor light.

“…The development of solar cells plays an important role in the area of solar energy conversion [1]. Since the first report by Oregan and Gratzel in 1991 [2], DSSCs have received massive attention owing to their relatively high energy conversion efficiencies along with their low projected production cost and simple fabrication process [3,4,5,6]. However, the traditional fabrication process of dye-sensitized solar cells (DSSCs) uses liquid electrolytes, which leads to long-term stability problems because of the leakage and volatility of liquid electrolytes [7,8].…”

To obtain new highly efficient and stable quasi-solid dye-sensitized solar cells (QS-DSSCs) that can meet the requirements for the large-scale commercial application of solar cells, we have developed a novel quasi-solid-state electrolyte, based on an electrospun polyvinylidene fluoride (PVDF) membrane. The structure and properties of electrospun PVDF membranes were characterized by scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET), thermogravimetric (TG), and mechanical testing. The results indicate that the electrospun PVDF membrane has a three-dimensional network structure with extremely high porosity, which not only acts as a barrier to prevent electrolyte leakage but also provides a channel for the transmission of ions in the electrolyte, thereby effectively guaranteeing the high photoelectric conversion efficiency of the cells. The membrane was observed to withstand the conditions of hot-press (110 °C), and exhibited good thermal stability and mechanical strength, which are critical for the long-term stability and safety of the cells. The photovoltaic characteristics and stabilities of QS-DSSCs were compared with DSSCs based on an ionic liquid electrolyte (L-DSSC). QS-DSSCs with an 80 μm thick nanofiber electrolyte membrane showed a conversion efficiency of 8.63%, whereas an identical cell based on the corresponding ionic liquid electrolyte showed an efficiency of 9.30%. The stability test showed that, under indoor and outdoor conditions, after 390 h, the L-DSSCs failed. Meanwhile, the QS-DSSCs also maintained 84% and 77% of the original efficiency. The results show that, compared to the liquid electrolyte, the design of the quasi-solid electrolytes based on electrospun PVDF nanofiber membrane not only demonstrates the high conversion efficiency of DSSCs but also enhances the stability of the DSSCs, which provides the possibility for the fabrication of solar cells with higher efficiency and stability.
