Conclusion

Photoacoustic allows simple nondestructive and noncontact measurement of the photovoltaic energy conversion efficiency and internal quantum efficiency of the photodiode. We can also determine the responsivity of the photodiode.

Using different frequencies we can obtain information about spatial distribution of heat generation and consequently about the processes within the sample.

We also showed that the presented theory is valid only for low modulation frequencies (below 20 Hz).

The frequency photoacoustic study concerning spatial distribution of heat sources in photodiodes is in progress and will be published separately later.
