Typical efficiencies range from 14% to 18% for a monocrystalline silicon PV cell.
The current-voltage (I-V) curve for a PV cell shows that the current is essentially constant over a range of output voltages for a specified amount of incident light energy. Figure 1: Typical I-V Characteristic Curve for a PV Cell Figure 1 shows a typical I-V curve for which the short-circuit output current, ISC is 2 A.
The basic characteristics of the photocell were tested and analysed through experiments by an optical control experimental platform, such as short circuit current, open circuit voltage, illumination characteristic, volt ampere characteristic, load characteristic, and spectral characteristic.
Using photocell experimental apparatus for data collection and analysis, then handling data by software, you can analyse characteristics of photocell; test results are consistent with the theory. After knowing the characteristics of the photocell, we can build an optical control circuit using photocell.
Other important characteristics include how the current varies as a function of the output voltage and as a function of light intensity or irradiance. The current-voltage (I-V) curve for a PV cell shows that the current is essentially constant over a range of output voltages for a specified amount of incident light energy.
