Cell Area: By increasing the area of the cell, the generated current by the cell also increases. The angle of incident: If the light falling on the cell is perpendicular to its surface, the power generated by it is optimum. Ideally, the angle should be 90o but practically it should be as close as 90o. The solar cell is a two-terminal device.

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).
During the development of solar cells or in industrial production, it is desirable to know already the quality of the absorber alone. Photoluminescence (PL) measurements of the absorber can provide information about the open circuit voltage and the fill factor, which the absorber is able to produce when made into a solar cell.
