The short-circuit current is the current through the solar cell when the voltage across the solar cell is zero (i.e., when the solar cell is short circuited). Usually written as I SC, the short-circuit current is shown on the IV curve below. IV curve of a solar cell showing the short-circuit current.
The basic characteristics of silicon photovoltaic cells are mainly studied, such as short-circuit current, photoelectric characteristics, spectral characteristics, volt ampere characteristics, time response characteristics and so on, and the application of silicon photocell can be realised.
Volt ampere characteristics When the input light intensity of silicon photocell is constant, the relationship between the output voltage and current of the photocell along with the change of load resistance is called the volt ampere characteristic. Load characteristics The photocell is used as a battery, as shown in figure 3.
3.3.2. Open Circuit Voltage Characteristic Test of Silicon Photocell. Under the condition of the Fig2 circuit, the illuminance on photocell is controlled by illumination meter. Adjust illumination to the minimum, connected to the illumination meter, DC power to the minimum, open the illumination meter, at this time the meter readings should be 0.
For an ideal solar cell at most moderate resistive loss mechanisms, the short-circuit current and the light-generated current are identical. Therefore, the short-circuit current is the largest current which may be drawn from the solar cell. The short-circuit current depends on a number of factors which are described below:
On the contrary, when the intensity of the light on the silicon photocell is changed from strong to weak, when the illuminance reaches a certain value, the light-emitting diode will emit light, thus the design of the light controlled switch circuit based on the silicon photocell is realized.
