Abstract
Photoacoustic (i.e., photocalorimetric) measurements on photovoltaic devices can directly yield their energy conversion efficiency. This is illustrated for a Si solar cell, for which case excellent agreement is found with normal electrical measurements. In addition, the photoacoustic spectra under load and at open-circuit conditions are reported and compared with the cell’s spectral response. Together, such measurements can provide information on the wavelength dependence of the cell performance as well.Keywords
