Evaluation of the Thermoelectric Properties and Thermal Conductivity of CH₃NH₃PbI_3-x Cl _x Thin Films Prepared by Chemical Routes.

ABSTRACT: The thermoelectric properties and thermal conductivity of mixed-phase CH₃NH₃PbI_3-x Cl _x thin films have been reported as a function of temperature, ranging from room temperature (RT) to 388 K. Thermoelectric study confirms that CH₃NH₃PbI_3-x Cl _x is a p-type material and the charge carrier transport in CH₃NH₃PbI_3-x Cl _x is governed by polarons and the thermal scattering process. The Peltier function and power factor are found to decrease initially up to ∼325 K, after which they increase with increasing temperature. The position of (E _F - E _V) of all samples drops down sharply to zero
