Question

The curve represents the $I-V$ characteristics of which optoelectronic device?

• A. Solar Cell
• B. Photo-diode
• C. Light Emitting Diode (LED)
• D. None of these

Answer 1

The correct option is A Solar Cell

1.The span of the solar cell $I-V$ characteristic curve ranges from short circuit current $I_{sc}$ at zero output volts, to zero current at te full open circuit voltage$V_{oc}$

2.With the solar cell open circuited that is not connected to any load, the current will be at its maximum(zero) and the voltage across the cell is at its maximum known as open circuit voltage $\left(V_{oc}\right)$

3.At the other extreme when the solar cell is short circuited that is the positive and negative loads connected together, the current flowing out of the cell reaches its maximum known as short circuit current$I_{sc}$
