A Si sample with 10¹5 cm³ donors is uniformly optically excited at room temperature in such a way that 10¹⁹ cm³³ EHPs (Electron-Hole pairs) are generated per second. Find the separation of the quasi-Fermi levels and the change of conductivity upon shining the light. Electron and hole lifetimes are both 10 µs and Dp = 12 cm²/s.
