Preliminary results are presented of the photoacoustic phase angle dependence, for a Si solar cell, on load resistance, illumination intensity, and photon energy. The data are interpreted using a simple, phenomenological model that assigns the thermal loss mechanisms occurring in the photovoltaic device to the diffused (top) layer, the junction region, and the base of the cell.
