Based on the experimental and theoretical signals of an open photoacoustic cell operating with modulation frequencies from 20 Hz to
20 kHz, a significant contribution of photogenerated excess carriers on the thermal and thermoelastic responses of an n-type silicon plate is
observed for the very first time. This is achieved by comparing the measured amplitude and phase of the photoacoustic signal with their
corresponding theoretical thermoelastic counterparts, for high enough modulation frequencies mainly. It is shown that the amplitude of the
thermoelastic component of plasma-thin samples varies about two orders of magnitude with respect to the corresponding one of
plasma-thick samples. Furthermore, we find a maximal temperature difference ΔT =− 35 nK between the illuminated and non-illuminated
sample surfaces, which shows that thin silicon plates with excess carriers could be used as heat sinks.
