Summary Dye‐sensitized solar cells (DSSCs) are more attractive than silicon solar cells due to their low dependency on light intensity so that they can perform both indoor and outdoor with low‐level lightings. DSSC's global revenue exceeded 16 million USD in 2014 for emerging portable charging, solar bags, and wireless keyboards. However, on‐grid DSSC modules are still under R&D for massive commercialization to improve their long‐term stability and safety issues due to the liquid electrolyte leakage. Therefore, quasi‐solid‐state electrolytes (QSE) have been proposed as a novel alternative to overcome the limitations stated above since 2001. Here, we deliver a short outline of the QSE properties, which are linked with the performance of DSSC in terms of different types of QSE structures: gel, hydrogel, and aerogel. Furthermore, these QSE structures are classified under bio and non‐bio materials. Finally, the impact, outlook, and future prospects of QSE‐DSSC are included as a conclusion in this review.

“…DSSCs have garnered significant attention from researchers due to their attributes such as thin-film construction, high efficiency, straightforward fabrication, and environmentally friendly processing [5][6]. DSSCs typically consist of two conducting glass substrates and three crucial components: a porous semiconductor with a band gap sensitive to dye molecules, a counter electrode, and a redox electrolyte [7][8][9].…”

This comprehensive research has explored the potential of enhancing dye-sensitized solar cells (DSSC) by harnessing environmentally friendly natural dyes, such as chlorophyll pigments from pandanus (664.1 nm) and papaya leaves (664.0 nm), as well as betacyanin pigments from sappan-mangosteen (536.2 nm). Electrochemical analyses elucidated the energy band gaps, revealing a hierarchy with the smallest band gap observed for papaya leaves (1.387 eV), followed closely by sappan-mangosteen (1.389 eV) and pandan leaves (1.396 eV). This research effectively addressed the persistent issue of electrolyte leakage in DSSC development by introducing a polymer electrolyte derived from polyvinylidene fluoride (PVDF) through electrospinning and phase inversion techniques. SEM characterization results and thermogravimetric analysis underscored the superior characteristics and high thermal stability of the PVDF nanofiber polymer for DSSC applications. The study's pivotal findings underscore the remarkable DSSC performance achieved with chlorophyll pigment from papaya leaves, reaching 1.31% efficiency without a polymer electrolyte. Moreover, the sappan-mangosteen dye emerged as a promising contender with the highest efficiency values when applied with polymer electrolyte, recording rates of 1.17% for PVDF NF and 0.95% for PVDF, which are notably comparable to the efficiency of liquid electrolyte at 1.26%.

“…High energy conversion efficiency and low electricity production costs compared to silicon solar cells make DSSC attracts a lot of research interest [6]. DSSC consists of two conductive glasses with three important components: a wide band gap semiconductor porous film with a dye molecule as a photosensitizer, a platinum (Pt) counter electrode, and a redox electrolyte [7][8][9]. In the DSSC system, photo-excitation of the dye produces electrons which are then injected into the titanium dioxide (TiO 2 ) semiconductor conduction band, while the redox reaction occurring at the interface of electrons is transferred to the counter electrode by an external circuit will result in regeneration of the oxidized photosensitizer dye [1].…”

The potential of dye-sensitized solar cells (DSSC) as an alternative to depleting fossil fuels has been investigated. To optimize performance and efficiency, the effectiveness of PVDF and PVDF nanofiber (NF) membrane-based electrolytes in suppressing solvent leakage and evaporation in liquid electrolyte systems was evaluated. SEM results for PVDF NF membranes showed the formation of a network with a three-dimensional structure with a diameter of 100–300 nm and an average thickness of 0.14 mm. The Infrared (IR) spectrum shows the electrolyte and polymer-PVDF interactions. Differential Scanning Calorimetry (DSC) curve shows the melting transition of PVDF NF 7.66% lower than PVDF. Efficiency and resistance of DSSC based on natural dyes as measured by multimeter and Electrochemical Impedance Spectroscopy (EIS) at a solar intensity of 100 mW/cm2 showed the highest efficiency of anthocyanin-based DSSC from telang (Clitoria ternatea L.) flower extract. Its use as a photosensitizer in an electrolyte system based on PVDF NF membranes resulted in an efficiency that was not significantly different from that of liquid electrolytes (1.69%).
