These solar cells produce a voltage of 0-5 volts. These are very suitable to be used as control voltage (CV) in the Modular Synthesizer. For example, a changing light source can influence a filter (VCF), the pitch of an oscillator (VCO) or the volume of an amplifier (VCA). When an autonomous patch is influenced by external sensors, it is also called an interactive generative system.

Another possibility is to feed the solar cell directly into an audio amplifier. Then e.g. the frequencies of LED’s can be made audible. Click the link below to watch an example.
