In this paper, we report on the synthesis of solid polymer electrolytes (SPEs) on the basis of 95 wt.% PEO and 5 wt. of anhydrous cobalt (II) chloride hexahydrate (CoCl2 6H2O), hereafter called PCL5, by the spin-coating technique using different types of glass (normal, quartz, ITO) substrates. The PCL5 electrolyte exhibits the highest conductivity and the lowest optical bandgap and hence, it was selected as a component to fabricate the organic single-layer device. |
