TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Compound: The zwitterionic compound is preferably of formulae (B,C), and forms a complex with electrolyte.    TECHNOLOGY FOCUS - ELECTRONICS - Preferred Component: The photovoltaic cell charge carrying layer (A) further comprises solvent, redox system, and lithium salt as electrolyte. Layer (A) comprises 10 volume fraction or more of each complex (B) and redox system, preferably 60 volume fraction. Layer (A) comprises 5 volume fraction of solvent, preferably 70 volume fraction. Preferred Definitions:    n = at least 1, preferably 20 and more preferably 2 or 3;    x = 20, preferably 15 and more preferably 10;    R1 = cationic nitrogen-substituted heterocyclic containing two or more nitrogen atoms, and cationic alkyl substituted ammonium, cationic substituted guanidinium or cationic phosphonium group, preferably alkyl imidazolium, piperidinium, pyridinium, morpholinium, pyrimidinium, pyridazinium, pyrazinium, pyrazolium, pyrrolinium, thiazolium, oxazolium, triazolium penta alkyl guanidinium or asymmetric tetra alkyl ammonium, and more preferably alkyl imidazolium;and    R3 = H, halo or 1-6C alkyl optionally substituted with halo group(s), preferably H, F or 1-6C alkyl group optionally substituted with one or more F, and more preferably CF3.    EXAMPLE - Acetone (200 ml) and 1-methyl imidazole (in g) (15.07) were provided in a flask, and cooled to 0 degrees C in an ice bath. A solution obtained by dissolving 1,4-butane sulfone (25) in acetone (200 ml), was slowly dripped into the obtained mixture. After addition, ice bath was removed, and reaction mixture was stirred for 5 days. The product was precipitated from acetone, and separated by suction filtration. The obtained precipitate was washed with acetone, and vacuum dried at 60 degrees C for 24 hours, to obtain 1-methyl-3-(4-sulfoxybutyl) methyl imidazolium zwitterion of formula (B) having melting point of 235-237 degrees C. An electrolyte solution was prepared using the obtained zwitterion, t-butyl pyridine, iodide and gamma-butyrolactone. A flexible dye sensitized solar cell having efficiency of 5.2% at solar irradiation of 100 mW/cm2, was prepared using the electrolyte solution.
