Organic thermoelectric device,Rotary Kelvin Probe

In this study, we aim to realize a novel organic thermoelectric device utilizing charge-transfer (CT) complexes that induce charge separation with thermal energy at room temperature. We are currently investigating the charge separation mechanism at the CuPc/F₁₆CuPc interface using rotating Kelvin probe (RKP). In this presentation, we will discuss the effects of the surface potential shift of CuPc under vacuum and the energy bandgap width at the CuPc/F₁₆CuPc interface on charge separation efficiency.
