PV cell parameters are usually specified under standard test conditions (STC) at a total irradiance of 1 sun (1,000 W/m2), a temperature of 25°C and coefficient of air mass (AM) of 1.5. The AM is the path length of solar radiation relative to the path length at zenith at sea level. The AM at zenith at sea level is 1.
The solar cell characterizations covered in this chapter address the electrical power generating capabilities of the cell.
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).
Several factors determine the efficiency of a PV cell: the type of cell, the reflectance efficiency of the cell’s surface, the thermodynamic efficiency limit, the quantum efficiency, the maximum power point, and internal resistances. When light photons strike the PV cell, some are reflected and some are absorbed.
