Light of energy

shines onto an

area

of a photoconductor made of doped silicon.  The silicon has an energy gap and in this system has a quantum efficiency

and a

photoconductive gain of

. The photon flux .

 

Plank’s constant , the speed of light

and the

proton charge

.

 

Calculate the photocurrent in the photoconductor assuming

all photons are absorbed.  State your

answer in mA, rounding to the nearest integer value if necessary.
