ELECTROACOUSTICS IN A SILICON SOLAR-CELL

We present electroacoustic measurements of a p/n(+) silicon solar cell as a function of the stimulating potential modulation frequency, gain ing information on the different power dissipation sources within the device by means of thermal depth profiling. Theoretical calculations o f the electroacoustic signal based on a reinterpretation of the Rosenc waig and Gersho model have also been performed, and the results of the se calculations have been compared to the experimental data.
