Irradiance intensity dependence of the lumped parameters of the three diodes model for organic solar cells. 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. A simple equivalent circuit model for a PV cell consists of a real diode in parallel with an ideal current source. The experimental work of Masaki and Tatsuo [5] their allowed to deduct To understand the electronic behaviour of a solar cell, it is useful to create its model which is electrically equivalent at the solar cell. The performance of PV devices is often times modeled with equivalent circuits. 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. Because no solar cell is ideal, a shunt resistance and a series resistance component are therefore added to the model to have the equivalent circuit. Tran, V.H.
