题目内容

The \(V_{mp}\) and \(J_{mp}\) of a non-ideal solar cell are given in the plot above. The area of the solar cell is \(4 cm^2\). Having in mind the equivalent circuit of the non-ideal solar cell, calculate the current in \(mA\) at the shunt branch if \(R_{sh}=0.04 \Omegam^2\) and \(R_s=2.810^{-4} \Omega*m^2\) when the solar cell is operating at the maximum power point.According to your answer above, calculate how much power in \(mW\) is dissipated due to shunting of the solar cell at the maximum power point. Hint: Remember two things: (1) the relation between power, current and voltage and (2) Ohm's law! ______
