This study examines the interactions of piezoelectric, photothermal, and thermoelastic wave phenomena in orthotropic semiconductors subjected to thermal regulation via water. This study presents a model for coupling heat and moisture transport alongside photo-hydroelectricity. mechanical deformation induces the piezoelectric effect, initiating carrier density (plasma) waves by generating a polarization charge. At present, photothermal effects, caused by light absorption, facilitate the formation and propagation of plasma waves. The interplay of moisture and temperature under hygrothermal circumstances adds complexity to material behavior, affecting the formation and propagation of plasma waves. The normal mode technique produces analytical formulations for the transient response of temperature variation, moisture distribution, plasma, displacement, and stress components during continuous heat and moisture flow at the semiconductor surface. The research employs advanced mathematical techniques and computational simulations to demonstrate the influence of piezoelectricity, photothermal, and hygrothermal on primary physical field wave propagation. The numerical data is employed to graphically represent and calculate the hygrothermal fields and stress response in photo-hygrothermoelastic materials, including fluctuations in moisture content and time.
