What is the primary function of a photovoltaic source circuit?

The primary function of a photovoltaic source circuit is to generate electricity. Photovoltaic cells, commonly known as solar cells, convert sunlight directly into electrical energy through the photovoltaic effect. When sunlight hits the semiconductor material in the solar cells, it causes the electrons to become energized and flow, creating an electric current. This generated electricity can be used immediately to power electrical loads or can be directed into a storage system, but the fundamental role of the photovoltaic source circuit itself is the production of electricity from solar energy.

The other choices relate to functions associated with solar technology but do not define the primary purpose of a photovoltaic source circuit. For instance, converting voltage pertains to the role of inverters, measuring current is a task for monitoring devices or meters, and storing energy is the function of batteries or other energy storage systems. Each of these supports the overall solar energy system but does not define what a photovoltaic source circuit primarily does.
