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 \(R_{sh}=0.04 \Omega*m^2\) and \(R_s=2.8*10^{-4} \Omega*m^2\) when the solar cell is operating at the maximum power point. ______
