Silicon solar cell degradation due to solar fluxes

[hamzaaaa]

I am trying to find the Absorbed dose for Silicon cells on a geostationary satellite from a period of (1996 to 2005)

The Equation I have is:
D(rad) = 1.68e-8 *((1/ρ)*dE/dx) * Phi

Where: D is absorbed dose and units are (100 ergs/g or 0.01 J/Kg)

(1/ρ)*dE/dx = (MeV*cm^2)/g

Phi=incident fluence= particle * cm^-2

I have the following set of data as you can see in the attachments. And I want to calculate 'D' for Electron Fluence. In the text file the units of Fluence is given by Electrons/cm2-day-sr.

How to convert them to particle * cm^-2 ?

Is this the right approach by the way?

The answer to your question is yes, this is the right approach. To convert the fluence from electrons/cm2-day-sr to particles/cm2, you need to multiply it by the number of particles in one electron (1.602 x 10-19 Coulombs). This will give you the particle fluence in particles/cm2.
