Development of novel Nano polymer composite material for solar energy conversion

Abstract EN

PVA: Co5(OH)8(NO3)2·2H2O polymer composite has been produced by casting of aqueous solution of mixed composite component.

The nano polymer composites were characterized using structure techniques; XRD, SEM, FT-IR and TGA.

The results indicated the formation composite without PVA degree of crystallinity variation.

The measurements of electrical conductivity for the composites illustrated domination of ion conduction with activation energy (0.65-0.90) eV.

The optical absorption illustrated an absorption peak around (530-540) nm wich suggest electronic direct transition via energy gap width (1.90-2.16) eV.

The electrochemical illustrated electrochemical band gap (1.97-3.26) ev.
