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.

The I-V characteristics may be shown to be different for different solar insulations and temperatures. If the I-V characteristics change from time to time then the respective P–V characteristic curves also change and so as the peak power point. A solar cell''s peak power point is shown in Fig. 3.15.
Specific performance characteristics of solar cells are summarized, while the method(s) and equipment used for measuring these characteristics are emphasized. The most obvious use for solar cells is to serve as the primary building block for creating a solar module.
Solar cells convert power of sunlight into electric power. As an introduction, therefore, Chapter 1 is devoted to a brief characterization of sunlight and basic electric parameters of solar cells. The power of sun is given in terms of the solar constant, the power spectrum and power losses in earth atmosphere expressed by the so-called air mass.
The I-V characteristics of a solar cell are actually the graph plotted between the current and voltage of the solar cell at a particular temperature and intensity of radiation. I-V characteristic curves help in providing information regarding the operating conditions where a solar panel can perform to its optimum capacity known as maximum peak power point (MPP).

The power output at the maximum power point under strong sunlight (1 kW/m2) is known as the ‘peak power’ of the cell. Hence photovoltaic panels are usually rated in terms of their ‘peak’ watts (Wp). The fill factor (FF), is a measure of the junction quality and series resistance of a cell. It is defined as
Some of these covered characteristics pertain to the workings within the cell structure (e.g., charge carrier lifetimes) while the majority of the highlighted characteristics help establish the macro per-formance of the finished solar cell (e.g., spectral response, maximum power out-put).
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).
The slope of the exponential term is usually significantly larger than 60 mV per decade, i.e. a higher potential than for an ideal solar cell is needed to increase the current by one order of magnitude. The ratio of the measured slope and 60 mV per decade is called the ideality factor and is equal to one for an ideal solar cell.
Under STC the corresponding solar radiation is equal to 1000 W/m2 and the cell operating temperature is equal to 25oC. 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).
