Not all of this current is available … Solar cells are a form of photoelectric cell, defined as a device whose electrical characteristics – such as current, voltage, or resistance– vary when exposed to light. A solar cell (also known as a photovoltaic cell or PV cell) is defined as an electrical device that converts light energy into electrical energy through the photovoltaic effect. The I-V characteristics depend on the intensity of the incident radiation and also the operating point (external load) of the cell. The diagram of the equivalent circuit is indicated on following figure: Figure 3. There's an ideal current source which is driven by light intensity.

Castro, F.A. 2. If you want to carefully analyze the behavior of a circuit that includes a solar (aka photovoltaic, or PV) cell, you need to use an “equivalent circuit”—i.e., you need to replace the cell with a group of basic components that can produce similar electrical behavior.
