Determination of glass transition temperature using temperature dependent signal from a cryogenic photopyroelectric instrument

•A photopyroelectric device for 90 K to ambient thermal studies was constructed.•Temperature controlled LED was used to heat the sensor/sample interface.•The thermal diffusion equations for FPPE configuration were solved.•Sensor used was LiTaO3 with an ITO layer on one side and gold on other.•The gl...
