How do you calculate a short circuit current in a solar cell?
Let’s take an example, a solar cell has a current density of 40 mA/cm2 at STC and an area of 200 cm2. Then the short circuit current can be determined as follows; ISC = Jsc × Area = 40 mA/cm2 × 200 cm2 = 8000 mA = 8 A Open circuit voltage is the maximum voltage that the cell can produce under open-circuit conditions.
What is a solar cell equation?
The model will be used to derive the so-called solar cell equation, which is a widely used relation between the electric current density I leaving the solar cell and the voltage V across the converter. For this purpose, we use the relation for generated power P = I ⋅ V and Eq. (127) and we obtain: By using Eqs. (128), (129) we derive:
How do you calculate voltage across a string of solar cells?
When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts.
How do you find the current density of a solar cell?
The current density is obtained by dividing I SC by the area of solar cell (A).The current density is normally referred by symbol, ‘J’, therefore, the short circuit current density, Jsc is given by I SC/ A. Open circuit voltage (Voc): It is the maximum voltage that a solar cell produce.
What is the value of open-circuit voltage in a solar cell?
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 value of short circuit depends on cell area, solar radiation on falling on cell, cell technology, etc. Sometimes the manufacturers give the current density rather than the value of the current.
