In this paper, we have examined the conductivity and interaction studies of ammonium and imidazolium based ionic liquids ILs with the newly synthesised low bandgap polymer Poly2-heptadecyl-4-vinylthieno3,4-dthiazole PHVTT. Use of low bandgap polymers is the most suitable way to harvest a broader spectrum of solar radiations for solar cells. But, still there is lack of most efficient low bandgap polymer. In order to solve this problem, we have synthesised a new low bandgap polymer and investigated its interaction with the ILs to enhance its conductivity. ILs may undergo almost unlimited structural variations; these structural variations have attracted extensive attention in polymer studies. The aim of present work is to illustrate the state of art progress of implementing the interaction of ILs protic and aprotic ILs with newly synthesised low bandgap polymer. In addition to this, our UV-Vis spectroscopy, confocal Raman spectroscopy and FT-IR spectroscopy results have revealed that all studied ILs tributylmethylammonium methyl sulfate N1444MeSO4 from ammonium family and 1-methylimidazolium chloride MimCl, and 1-butyl-3-methylimidazolium chloride BmimCl from imidazolium family have potential to interact with polymer. Our semi empirical calculation with help of Hyperchem 7 shows that protic IL MimCl interacts strongly with the low bandgap polymer through the H-bonding. Further, protic ILs shows enhanced conductivity than aprotic ILs in association with low bandgap polymer. This study provides the combined effect of low bandgap polymer and ILs that may generate many theoretical and experimental opportunities.
