PEDOT:PSS and Ni-based Thermoelectric Generator for Solar Thermal Energy Storage

Abstract

Searching an inexpensive and effective way to improve the thermoelectric properties of organic materials can greatly expand the practical application of thermoelectric thin film generator. Here, we adopt the triple treatment of ethylene glycol ((CH2OH)2) and ethanol(C6H5OH) doping and (CH2OH)2 dedoping to tune the micro stacking structure of PEDOT:PSS, obtaining PEDOT:PSS thermoelectric film material with the highest power factor (PF) up to 330.597 μWm-1,which stems from the high Seebeck coefficient (S) and conductivity (σ). Furthermore, we have made the thermoelectric generator to explore the photothermal conversion process of solar energy. The maximum power output of the self-made module device with solar energy as the heat source is 9.8 nW. This work is a prospective experiment for development of the solar energy photothermal conversion base on the thin film and device.
