In this paper, all the models of PV cell, namely ideal single-diode model, single-diode R s model, single-diode R p model, the two-diode model, and the three-diode model, have been discussed. SPICE simulation is done to evaluate the impact of model parameters on the operation of PV cell. The effects of the parameters are discussed.
A typical circuit for measuring I-V characteristics is shown in Figure-2. From this characteristics various parameters of the solar cell can be determined, such as: short-circuit current (I SC), the open-circuit voltage (V OC), the fill factor (FF) and the efficiency. The rating of a solar panel depends on these parameters.
A solar cell is a semiconductor device that can convert solar radiation into electricity. Its ability to convert sunlight into electricity without an intermediate conversion makes it unique to harness the available solar energy into useful electricity. That is why they are called Solar Photovoltaic cells. Fig. 1 shows a typical solar cell.
Typically a solar or photovoltaic cell has negative front contact and positive back contact. A semiconductor p-n junction is in the middle of these two contacts like a battery. If these two sides are connected by an external circuit, current will start flowing from positive to negative terminal of the solar cell. This is basic working principle of a solar cell. For silicon, the band gap at

The solar cell parameters are as follows; Short circuit current is the maximum current produced by the solar cell, it is measured in ampere (A) or milli-ampere (mA). As can be seen from table 1 and figure 2 that the open-circuit voltage is zero when the cell is producing maximum current (ISC = 0.65 A).
A semiconductor p–n junction can be made to operate as a solar cell. Figure 1 shows the basic structure of a PV cell. When light is incident on the cell, the photons of light generate free electron–hole pairs which are then attracted toward the junction. Figure 2 illustrates the operation of the solar cell.
