Consider the solar cell described in Problem $14\mathrm{.}10.($a$)$ The generated photocurrent is IL $10$ mA$.$ Determine $($i$)$ the open$-$circuit voltage and $($ii$)$ the maximum power output. $($b$)$ The solar cell now uses a solar concentrator such that the photocurrent increases by a factor of $10.$ Determine the new values of $($i$)$ open circuit voltage and $($ii$)$ maximum power output. $($c$)$ Determine the ratio of maximum power from part $($b$)$ to that from part $($a$).$
