“…They are, therefore, unsuitable for long-term use, especially at the electrolyte injection holes [40]. The use of silicone rubber or the process of glass frit bonding has been proposed as an alternative to organic sealants due to their high moisture, heat, UV, and electrolyte tolerance [41]. Glass frits in particular provide airtight hermetic encapsulation, but this process generally requires high temperatures of over 300 • C. This is not feasible as components such as the electrolyte cannot withstand such high temperatures.…”

Dye-sensitized solar cells have been under development for the last three decades but are yet to see the market. This has been attributed to stability issues of the electrolyte in the cell. Electrolytes can be liquid, quasi-solid, or solid. Liquid electrolytes were the first to be developed and, therefore, have been subject to radical revisions in both composition and applicability. They have shown the best power conversion efficiencies but have poor thermal stability. Although quasi-solid and solid-state electrolytes were developed to overcome these stability issues, they too have their limits. The aim of this paper is to explore the development of liquid electrolytes, outlining the current state of the technology and considering their potential in the photovoltaic market.

“…(i) the monolithic structure contains only one FTO substrate, which gives a clear advantage in terms of material cost; (ii) the anode and cathode terminals in the sandwich structure are located on two different substrates, while in monolithic DSSC both terminals are located on the same substrate; and (iii) the sealant in conventional DSSC is typically serve as spacer, whereas in monolithic structure the ZrO2 layer [12] serve as a spacer to separate the TiO2 layer (anode) and counter-electrode side layer (cathode). With the monolithic design, the fabrication process is more adaptable for up scaling because no alignment is necessary when it comes to cell assembly [13]. The photographs of the electrode with carbon and platinum catalyst are shown in Figure 2.…”

Dye-sensitized solar cells (DSSC) are widely developed due to their attractive appearance and simple fabrication processes. One of the challenges that arise in the DSSC fabrication involves high material cost associated with the cost of conductive substrate. DSSC with monolithic configuration was then developed on the basis of this motivation. In this contribution, titanium dioxide-based monolithic type DSSCs were fabricated on a single fluorine-doped transparent oxide coated glass using porous ZrO2 as spacer. Herein, the catalytic material for the counter-electrode was varied using carbon composite and platinum in order to analyze their effect on the solar cell efficiency. Four-point probe measurement revealed that the carbon composite exhibited slightly higher conductivity with a sheet resistance of 9.8 Ω/sq and 10.9 Ω/sq for carbon and platinum, respectively. Likewise, the photoconversion efficiency of the monolithic cells with carbon counter-electrode almost doubled the efficiency of the cells with platinum counter-electrode. Our results demonstrate that carbon could outperform the performance of platinum as catalytic material in monolithic DSSC.

“…The use of solvents with low volatility, such as ionic liquids, 3-methoxypropionitrile (MPN), γ-butyrolactone, propylene carbonate, propionitrile, sulfolane, butyronitrile, to name a few, is the preferred strategy to improve DSSCs stability. Nevertheless, reports of electrolyte leakage through the device sealing are common; − robust and hermetic encapsulation is then essential for a long-lasting device. − Moreover, hermetic encapsulation is required and relevant for the trustworthy study of extrinsic and intrinsic factors responsible for device degradation …”

Hermetic encapsulation is crucial for the lifespan of dye-sensitized solar cells (DSSCs). Sealing with glass frits provides hermetic encapsulation and extends the lifetime of DSSCs yet so far has been performed at inconveniently high temperatures, above 300 °C, not compatible with most DSSCs materials. This study develops a new laser-assisted glass frit sealing process at low process temperature of 110 °C. For the first time, glass frit encapsulation becomes fully compatible with most heat-sensitive materials used in DSSCs and did not affect the device performance after sealing. Hermeticity and durability of the seal complies with MIL-STD-883 and IEC61646 standards. Unique glass frit sealing configuration, parameters of the laser beam, and sealing protocol are disclosed. The developed glass frit sealing is fully compatible with liquid junctions DSSCs based on iodine and cobalt mediators and the resulting devices showed 1000 h of stability under simulated solar light according to ISOS-L-2 testing conditions. The new low-temperature sealing method allows a simplified DSSCs fabrication with a fully hermetic and durable seal and extends the applicability of glass frit sealing to most types of the DSSCs devices.
