Answer to Question #85164 in Physics for Matias

Question

I have a spreadsheet contains the Internal Quantum Efficiency data as a function of wavelength for a silicon solar cell with a shallow junction, intended for space use. Use the solar cell model discussed in the lectures, assuming an infinitely thick base and a negligible contribution from the emitter, to calculate IQE. By fitting your results to the data in the region 700-1100 nm, estimate the electron diffusion length in the base (in μm).

What methodology should I follow? what equations?
