This paper emerged out of analyzing simultaeously obtained microwave differential absorption profiles for perovskite thin film (methyl ammonium lead iodide) 300nm thick spun on glass substrate.  The film was photoexcited using a 532 nm 0.69ns pulsewidth pulsed laser and the RF voltages obtained in the averaged signal are analyzed to point out differences in the averaged signal parameters (conductance and charge transport realted parameters) for a new and an aged perovskite sample.
