Abstract

The electroacoustic technique has been used to investigate thermal dissipation processes in p-n+ Si solar cells. The acoustic signal has been measured as a function of the amplitude and frequency of the applied voltage modulation. Experiments can be understood using a vector model which takes into account the different locations of power generation and absorption in the cell.
