Such equivalent-circuit-based electron transmission analysis of dye-sensitized solar cells is very useful for the establishment of the link between cells’ electrical properties and its physical and chemical fabrication processes. One basic equivalent circuit model in common use is the single diode model, which is derived from physical principles (e.g., Gray, 2011) and represented by the following circuit for a single solar cell: To understand the electronic behavior of a solar cell, it is useful to create a model which is electrically equivalent, and is based on discrete ideal electrical components whose behavior is well defined.

PV cells are manufactured as modules for use in installations. 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. This is the equivalent circuit for a solar cell: The idea here is that the solar cell generates an internal current corresponding to the light intensity.
