Questiоn 4 A silicоn sоlаr cell operаting аt 300oK contains a p-n junction generated by an abrupt interface between a p region doped with 1017 cm-3 B atoms and an n-region with 1018 cm-3 of P. Electron-hole pairs generated outside the depletion region have to diffuse to the depletion regions to avoid recombination. Use the data at the end to estimate the minority carrier lifetime in the n and p doped Si layers. (2) the minority carrier diffusion lengths in the n and p-doped Si layers.
