A solar cell as reverse dark current of 10^-13A and photocurrent of 0.04A. The potential drop produce from this cell is 0.7V at room temperature. What is the overall current output of the solar cell?

Answer 1

The overall current output of the solar cell can be calculated by adding the dark current and photocurrent together.

Overall current output = dark current + photocurrent
Overall current output = 10^-13A + 0.04A
Overall current output = 0.04A

Therefore, the overall current output of the solar cell is 0.04A.

Answer 2

Calculate the open circuit voltage for given above.

Answer 3

The open circuit voltage of a solar cell can be calculated using the equation:

Open circuit voltage = potential drop across the cell - (dark current * cell resistance)

Given:
- Potential drop = 0.7V
- Dark current = 10^-13A
- Cell resistance = V/I = 0.7V / 0.04A = 17.5 ohms

Open circuit voltage = 0.7V - (10^-13A * 17.5 ohms)
Open circuit voltage = 0.7V - 1.75 x 10^-12V
Open circuit voltage = 0.7V

Therefore, the open circuit voltage for the given solar cell is 0.7V.
