“…These possible functional groups region can be seen were changed regarding to Figure due to the interaction effect between H + and electron lone pairs belongs to oxygen atoms carrier. Since glycerol is rich with hydroxyl groups in its structure, it can build effective networks with other components in the polymer electrolyte . Moreover, it has oxygen atom which is play role in a coordinated bond formation between cations.…”

A new membrane was synthesized containing pure alginate, crosslinking agent (CaCl 2 ), and plasticizer (glycerol). Characterization studies of the membrane were applied to determine the characteristics and morphology using field emission scanning electron microscope, EDX, FTIR, XRD, and atomic force microscopy analysis. The half-cell performance test of the membrane was verified by several tests, including proton conductivity and methanol permeability. The best membrane had high proton conductivity (10.1 3 10 23 S cm 21 ) and very low methanol permeability (1.984 3 10 27 cm 2 s 21 ), which consequently resulted in very high selectivity (5.0907 3 10 4 Ss cm 23 ). Glycerol had a positive modification and good influence on the alginate characteristics. Furthermore, the poor mechanical properties of the alginate biopolymer were enhanced by calcium chloride and glycerol inside the polymer. V C 2018Wiley Periodicals, Inc. J. Appl. Polym.

“…The photovoltaic parameters of polysaccharides with various salts (like NaI, KI and NH 4 I etc) are reported in literature and tabulated in Table 3. As expected, the most efficient biopolymer electrolyte based DSSCs contain I À /I 3 À redox couple [101][102][103][104][105][106][107][108][109][110][111][112][113][114][115][116][117]136,137,160,166,[178][179][180][181].…”

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.

“…[3][4][5] However, this iodide/triiodide based liquid electrolyte meets many obstacles such as corrosion, absorption of visible light and leakage of the liquid solvent. Thus, solid-state and quasi-solid-state electrolytes, such as polymer gel electrolyte, [6][7][8][9] organic hole-transporting materials, [10,11] inorganic p-type semiconductors, [12] and solvent-free polymer electrolyte [13,14] have been proposed as alternatives to the liquid electrolytes. Unfortunately, the efficiency of DSSCs using solid-state materials was still unsatisfactory compared with that achieved by the liquid electrolyte, due to the low charge transport ability of the solid-state electrolyte and poor contact of the electrolyte with the dye coated TiO 2 surface.…”

In this study, a novel bifacially active transparent dye-sensitized solar cell (DSSCs) assembled with a transparent poly(3,4-ethylenedioxythiophene) (PEDOT) counter electrode and a colorless iodine-free polymer gel (IFPG) electrolyte was developed. The IFPG electrolyte was prepared by employing an ionic liquid (1,2-dimethyl-3-propylinmidazolium iodide, DMPII) as the charge transfer intermediate and a polymer composite as the gelator without the addition of iodine, exhibiting high conductivity and non-absorption characters. PEDOT electrodes were prepared via a facile electro-polymerization method. By controlling the amount of polymerization charge capacity, we optimized the PEDOT electrodes with high transparency and a favorable activity for catalyzing the IFPG electrolyte. The bifacial DSSCs device fabricated by this kind of transparent PEDOT electrode and colorless IFPG electrolyte showed a power conversion efficiency (PCE) of 6.35% and 4.98% at 100 mW cm -2 AM1.5 illumination corresponding to front-and rear-side illumination. It is notable that the PCE under rear-side illumination approaches 80% that of front-side illumination.Moreover, the device shows excellent stability as confirmed by aging test. These promising results highlight the enormous potential of this transparent PEDOT CE and colorless IFPG electrolyte in scaling up and commercialization of low cost and effective bifacial DSSCs.
