“…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].…”

“…Amylose is water soluble but Amylopectin is insoluble in cold water and swells in it thereby giving rise to a thick paste upon boiling with water.It is a biopolymer contains about 23% starch (20-25% amylose and 75-80% amylopectin). It is clear that adding KI in Arrowroot matrix enhances the ionic conductivity and conductivity maxima were obtained by doping NaI and KI concentration where conductivity value approaches at 6.7 Â 10 À 4 and 1.04 Â 10 À 4 S/cm, respectively [166,167]. Adding (GlycerolþLiCl) and KI in Sago Palm matrix enhances the ionic conductivity and conductivity maxima was obtained by adding LiCl where conductivity value approachedto 10 À 3 S/cm with LiCl [38] and 3.4 Â 10 À 4 S/cm for KI [136,137].…”

“…Conductivities of the order of 10 À 6 S/cm at room temperature were reported for chitosan with poly (ethylene oxide) PEO blends and doped with LiTFSI salt [101] and also for the complex formed by chitosan, poly (aminopropylsiloxane) (pAPS) and LiClO 4 [105]. Conductivity ranges from 10 À 5 and 10 À 4 S/cm were reported for proton-conducting polymer electrolytes, based on chitosan and ammonium salts (NH 4 NO 3 and NH 4 CF 3 SO 3 ) [183,188] and this value is in the range of 10 À 6 -10 À 4 S/cm for chitosan and κ-carrageenan containing ammonium nitrate-based film [18,19].…”

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.
