“…In this case, TiO 2 nanoparticles were used as fillers to decrease the crystallinity leading to an increase in ionic conductivity (10 À5 S cm À1 ) and consequently an efficiency of 4.2% at 65.6 mW cm À2 illumination. 211,216,217 Wu et al synthesized a polyelectrolyte based on polyvinyl pyridine and used it as a solid-state ionic conductor in ssDSCs. Based on a larger backbone cation poly(N-alkyl-4-vinylpyridine) (PNR4VPI) and a smaller anion I À , the polyelectrolyte showed low conductivity due to weak interactions between the cation and anion.…”

a b s t r a c tPhotovoltaic technologies represent one of the leading research areas of solar energy which is one of the most powerful renewable alternatives of fossil fuels. In a common photovoltaic application the batteries play a key role in storage of energy generated by solar panels. Although it will take time for dye sensitized solar cells (DSSCs) and batteries based on biopolymer electrolytes to take their places in the market, laboratory studies prove that they have a lot to offer. Most efficient DSSCs and batteries available in market are based on liquid electrolytes. The advantages of liquid electrolytes are having high conductivity and good electrode-electrolyte interface whereas, disadvantages like corrosion and evaporation limit their future sustainability. Biopolymer electrolytes are proposed as novel alternatives which may overcome the problems stated above. In this review, we focus on fabrication, working principle as well as up to date status of DSSCs and batteries using biopolymer electrolytes. The effects of structural and electrical properties of biopolymer based electrolytes on the solar energy conversion efficiencies of DSSCs and their compatibility with lithium or other salts in battery applications are summarized. Biopolymer electrolyte based DSSCs are categorized on the basis of types of additives and recent outcomes of author's laboratory studies on biopolymer electrolyte based DSSCs and batteries are also presented.

“…However, there are some problems such as leakage of the electrolytes, evaporation of the organic liquid solvent, and high temperature instability, which cause difficulties in sealing and performance degradation of DSSCs 3. Thus, the commercial exploitation of these devices needs the replacement of the liquid electrolyte by a solid or quasi solid‐state charge‐transport medium,4–7 which not only offers hermetic sealing and stability, but also reduces design restrictions and endows the DSSCs with shape choice and flexibility 8…”

ABSTRACT:The cross-linked poly(ethylene glycol) (PEG-1000) was prepared by condensation reaction with tetraethoxysilane (TEOS). Using the cross-linked PEG-1000 as polymer host, 0.60 M KI and 0.06 M I 2 as ionic conductors, an ionic conductivity of the polymer electrolyte was achieved 3.12 mS cm À1. Based on the optimized crosslinked PEG electrolyte, the best result of the quasi-solid state dye-sensitized solar cell (QS-DSSC) was the shortcircuit photocurrent of 11.87 mA cmÀ2 , the open-circuit photovoltage of 706 mV, the fill factor of 0.593 and the light-to-electricity conversion efficiency of 4.97% at 100 mW cm À2 (AM 1.5).
