“…The sheet resistance (Rs) comprises the contacts/wires and electrolyte resistance. The lower Rs value of I2-based electrolytes for DSSCs explained the slightly better FF [56,71,72,93]. A lower R1 and R2 for the I2-containing electrolytes versus the I2-free counterparts was correlated to the higher concentration of I -/I3 − at the photoanode interface [56,71].…”

“…Recently, we reported improved performance and stability (in both ambient and accelerated aging conditions) of I2-free DSSCs fabricated with TiO2 electrodes grown on flexible Ti substrate and polysiloxane ionic conductors as electrolytes [72]. We assumed that the in-situ generation of I3ions in I2-free DSSCs was sufficient for the DSSC operation.…”

Ionic liquids (ILs) consisting entirely of ions exhibit many fascinating and tunable properties, making them promising functional materials for a large number of energy-related applications. For example, ILs have been employed as electrolytes for electrochemical energy storage and conversion, as heat transfer fluids and phase-change materials for thermal energy transfer and storage, as solvents and/or catalysts for CO2 capture, CO2 conversion, biomass treatment and biofuel extraction, and as high-energy propellants for aerospace applications. This paper provides an extensive overview on the various energy applications of ILs and offers some thinking and viewpoints on the current challenges and emerging opportunities in each area. The basic fundamentals (structures and properties) of ILs are first introduced. Then, motivations and successful applications of ILs in the energy field are concisely outlined. Later, a detailed review of recent representative works in each area is provided. For each application, the role of ILs and their associated benefits are elaborated. Research trends and insights into the selection of ILs to achieve improved performance are analyzed as well. Challenges and future opportunities are pointed out before the paper is concluded.

Purpose The purpose of this paper is to introduce flexible dye-sensitized solar cells (FDSSCs). Design/methodology/approach In the third generation solar cells, glass was used as a substrate, which due to its high weight and fragility, was not possible to produce continuously. However, in flexible solar cells, flexible substrates are used as new technology. The most important thing may choose a suitable substrate to produce a photovoltaic (PV) device with optimal efficiency. Findings Conductive plastics or metallic foils are the two main candidates for glass replacement, each with its advantages and disadvantages. As some high-temperature methods are used to prepare solar cells, metal substrates can be used to prepare PV devices without any problems. In contrast to the advantage of high thermal resistance in metals, metal substrates are dark and do not transmit enough light. In other words, metal substrates have a high loss of photon energy. Like all technologies, PV devices with polymer substrates have technical disadvantages. Practical implications In this study, the development of FDSSCs offers improved photovoltaic properties. Social implications The most important challenge is the poor thermal stability of polymers compared to glass and metal, which requires special methods to prepare polymer solar cells. The second important point is choosing the suitable components and materials for this purpose. Originality/value Dependence of efficiency and performance of the device on the angle of sunlight, high-cost preparation devices components, limitations of functional materials such as organic-mineral sensitizers, lack of close connection between practical achievements and theoretical results and complicated fabrication process and high weight.
