An improved solar cell circuit model for organic solar cells. EQUIVALENT CIRCUIT OF A D YE-SENSITIZED SOLAR CELL 3.1. ; Djeffal, F.; Benyounce, B.; Charles, J.-P. An equivalent circuit approach to organic solar cell modelling. To understand the electronic behaviour of a solar cell, it is useful to create its model which is electrically equivalent at the solar cell. 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. The equivalent circuit for the most used solar cell model consists of a diode and a current source connected in parallel, as well as a shunt resistor and a series resistor , as shown in Figure 3. The statements, opinions and data contained in the journals are solely where. If 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.
