how do i make this pv model work
Close the circuit. You say you have a source of current, so where does that current go? Perhaps a resistor as a load?

Error using quad "Error using quad (line 75) The integrand function must return an output vector of the same length as the input vector."
There are two powers in that line and you have only replaced one. @(q,n0)((eq(q)) *^* 2+2*U*n0*(eq(q))) *.^* 0.5
