Visible light-induced enhancement in the Seebeck coefficient of PEDOT:PSS composites with two-dimensional potassium poly-(heptazine imide)

The Seebeck coefficient of the composites of PEDOT:PSS and two-dimensional poly-(heptazine imide) (KPHI) can be greatly enhanced after exposure to visible light. It is attributed to the light-induced electron transfer from KPHI to PEDOT:PSS.
