Asilicon (si) sample with 1016cm-3donors is optically excited such that 1019cm-3electron-hole pairs are created every second uniformly in the sample. the laser causes sample to heat up to 450k. find the quasi-fermi levels and the change in conductivity upon shining light onthe silicon sample. use following parametersof siliconif you need to: electron and hole lifetimes are 10μs for both, dp=12cm2/s, dn=36cm2/s and at t=300kni= 10
